* feat(summary): phase 1/5 SinkSite data model for primary sink-location attribution

Introduce SinkSite (file_rel, line, col, snippet, cap) carrying the
primary sink source-location through function summaries. Swap
SsaFuncSummary.param_to_sink and FuncSummary.param_to_sink from a coarse
Cap map to a deduped SmallVec<[SinkSite; 1]> per parameter, with a
backward-compatible cap_sites() helper and serde defaults so pre-phase-1
on-disk rows continue to deserialise cleanly.

Extraction: SinkSiteLocator bundles the tree/bytes/file_rel needed by
extract_ssa_func_summary; ParsedFile::extract_ssa_artifacts wires the
locator in for the persisted pass-1 path, while pass-2 intra-file
transient summaries fall back to cap-only sites (behavior unchanged).
Merge: GlobalSummaries::insert now unions sink sites with
(file_rel, line, col, cap) dedup via shared union_param_sink_sites
helper.

Database: JSON-serialised summary columns carry the new shape
automatically; no schema change needed.

Phase 2 will consume SinkSite in build_taint_diag() to overwrite the
caller-site Finding.line with the callee's sink line when resolved via
summary. Phase 1 keeps behavior unchanged: scanning
tests/benchmark/corpus/rust/cmdi/cmdi_indirect.rs still produces the
same (wrong) line 10 finding.

Adds round-trip tests covering SinkSite solo, SsaFuncSummary with sink
sites, legacy-JSON default handling for both summary types, and merge
dedup.

* feat(taint): phase 2/5 thread SinkSite into SsaTaintEvent and Finding

Plumb Phase 1's SinkSite through the event pipeline into Findings,
no output change yet.  SsaTaintEvent gains `primary_sink_site:
Option<SinkSite>`; when the main or callback sink-emission path has
non-empty `param_to_sink_sites`, filter to sites whose
`(line != 0) && (cap ∩ sink_caps != ∅)` and emit one event per
distinct site — the multi-primary collapse keeps each downstream
Finding single-primary.

Resolution: ResolvedSummary and SinkInfo gain mirror
`param_to_sink_sites` fields, populated from `SsaFuncSummary.param_to_sink`
(SSA + callback paths) and `FuncSummary.param_to_sink` (global paths).
Label, local-summary, and interop resolution paths leave the field
empty — they only ever had cap-level info to begin with.

Finding: new `primary_location: Option<SinkLocation>` with
`file_rel/line/col`.  `ssa_events_to_findings` maps
`event.primary_sink_site` → `Finding.primary_location`, filtering
cap-only sites (`line == 0`) to `None` so the (0,0) sentinel never
leaks to formatters.  Dedup key extended with the primary location
so multi-site events aren't collapsed back together.

Invariants (debug_assert!):
* every SinkSite reaching emission has `line != 0 && cap ∩ sink_caps
  != ∅` — enforced by the pick_primary_sink_sites* filters;
* every populated Finding.primary_location has `line != 0` AND
  non-empty `file_rel` — the cap-only → None translation upstream
  guarantees this.

Deliberately independent of `uses_summary`: that flag tracks whether
the *taint chain* used a summary, whereas primary attribution
requires only that the *sink* itself was summary-resolved.  A local
source reaching a cross-file sink produces `uses_summary=false`
alongside a populated primary_location — documented on
Finding.primary_location, covered by
`cross_file_sink_finding_carries_primary_location`.

build_taint_diag, SARIF/JSON/explanation formatters, and the
benchmark scorer remain untouched: finding.line still comes from
`cfg_graph[finding.sink]`, so cmdi_indirect.rs still reports line 10
and the benchmark's rs-cmdi-003 row still shows FN in the LOC column.

Tests: `cross_file_sink_finding_carries_primary_location` (proves
plumbing via a synthetic FuncSummary carrying a SinkSite at 42:5) and
`cross_file_sink_cap_only_site_leaves_primary_location_none`
(regression guard against cap-only sites surfacing).  All 1566 lib
tests + integration tests pass.

* feat(output): phase 3/5 consume primary sink location in diag + SARIF

When a finding's primary_location (populated in phase 2 from a callee
summary's SinkSite) names the dangerous instruction inside a callee
body, attribute the diagnostic line to that location instead of the
caller's call site. The call site is demoted to a Call step in
flow_steps, and a synthetic Sink step at the primary location is
appended so analysts still see the full trace.

Changes:
- Add scan_root parameter to build_taint_diag so file_rel can be
  resolved back to an absolute path via a shared resolve_file_rel
  helper. Empty file_rel (single-file scans where namespace == "")
  resolves to the file under analysis.
- Extend SinkLocation with snippet, carried from the upstream
  SinkSite so the formatter needs no second file read.
- Relax the ssa_events_to_findings debug_assert to allow empty
  file_rel, which is valid when scan root equals the file itself.
- SARIF: emit data-flow as codeFlows[0].threadFlows[0].locations[];
  locations[0] already reflects the primary sink position via the
  updated diag line/col.

Acceptance: scan on tests/benchmark/corpus/rust/cmdi/cmdi_indirect.rs
now reports line 5 (Command::new) as the primary sink, with the call
site at line 10 visible in flow_steps.

Two expect.json fixtures updated (must_match line_range widened):
- javascript/taint/context_sensitive_call: 12-14 -> 7-14 (line 8 is
  the real sink inside run()).
- rust/cfg/closure_async: 10-10 -> 10-11 (line 11 is Command::new
  inside the closure).

* feat(bench): phase 4/5 validate primary sink attribution across corpus

Extend the benchmark scorer and ground truth to lock in phase 3's
primary-location behavior, and add fixtures that exercise the new
capability end-to-end.

Scorer (tests/benchmark_test.rs):
- Add optional `expected_call_site_lines: Option<Vec<[usize; 2]>>` on
  Case. When present, score_location_level additionally requires at
  least one flow_step in the finding's evidence trace to fall within
  ±2 of the call-site range. When absent, the check is skipped —
  fully forward-compatible with existing fixtures.
- Retain ±2 tolerance on expected_sink_lines (compared against the
  now-primary Diag.line post-phase-3).

Ground truth edits:
- rs-cmdi-cross-001: expected_sink_lines [8,8] -> [9,9]. Line 8 is the
  transform::wrap call site (a cross-file propagator, not a sink);
  line 9 is Command::new, the real sink. The ±2 tolerance happened to
  mask this stale attribution but it was semantically wrong — phase 4
  is the right time to correct it. Also adds expected_call_site_lines
  [8,8] so the new field is exercised on an existing cross-file case.
- rs-cmdi-003: adds expected_call_site_lines [10,10] (run_cmd call).
  This fixture's sink (Command::new inside run_cmd at line 5) was the
  motivating case for phases 1-3; adding the call-site assertion
  guards against regression to caller-line attribution.

New fixtures:
- rust/cmdi/cmdi_indirect_multisink.rs (rs-cmdi-009): helper run_both
  takes two tainted params and invokes two Command sinks on
  consecutive lines. Locks in that primary line lands inside the
  helper (lines 5-6), not at the caller (line 12). Notes document
  that SinkSite is currently one-per-callee so both findings today
  collapse onto the first sink; expected_sink_lines=[5,6] and
  expected_call_site_lines=[12,12] stay valid either way.
- python/cmdi/cross_indirect_sink/{app.py,helper.py} (py-cmdi-cross-
  004): sink os.system lives in helper.py (cross-file), caller in
  app.py reads env source and calls run_cmd. Verifies phase 3's
  cross-file primary attribution: Diag.path = helper.py, Diag.line =
  5, with app.py:7 recorded in flow_steps as a Call step.

Acceptance:
- `cargo test --test benchmark_test -- --ignored --nocapture` passes.
- rs-cmdi-003 is TP/TP/TP (the target flip FN->TP at LOC). All
  pre-existing TP/TP/TP fixtures remain TP/TP/TP; 2 new fixtures are
  TP/TP/TP.
- Aggregate rule-level: TP=158 FP=10 FN=1 TN=97, P=0.940 R=0.994
  F1=0.966 on the 266-case corpus (was TP=156 FP=10 FN=1 TN=97 on
  264 pre-phase-4, delta is the +2 new cases both resolving TP).
- Full `cargo test` green (1566 lib tests + all integration tests).

* feat(taint): phase 5/5 lock Finding.primary_location contract via regression test

Add a regression test in src/taint/ssa_transfer.rs that wires up a synthetic
SsaFuncSummary with a SinkSite at other.rs:42:10 and drives the three
emission stages (pick_primary_sink_sites → emit_ssa_taint_events →
ssa_events_to_findings) against a minimal caller SSA body.  Asserts the
resulting Finding.primary_location is exactly that triple.

The existing integration tests in src/taint/tests.rs cover the coarse
FuncSummary path end-to-end through analyse_file.  This test locks in the
lower-level SSA-side plumbing so a future refactor that silently drops the
site between pick → emit → findings fails here rather than only at the
benchmark layer.

Also refreshes tests/benchmark/results/latest.json (timestamp only; rs-cmdi-003
remains TP/TP/TP and the aggregate P/R/F1 are unchanged from phase 4).

Closes the primary sink-location attribution feature (phases 1-5/5):
* Phase 1 — SinkSite data model on summaries.
* Phase 2 — SinkSite threaded into SsaTaintEvent and Finding.
* Phase 3 — diag + SARIF consume primary_location.
* Phase 4 — benchmark validates primary_call_site_lines across corpus.
* Phase 5 — regression test locks the event→finding contract.
