Closes the CLI side of the policy chassis fan-out. Before this commit,
CLI direct-engine writes bypassed Cedar entirely because the CLI never
called `Omnigraph::with_policy(...)` for non-`policy validate|test|explain`
subcommands. After this commit, every CLI direct-engine writer
(change, load, ingest, branch create/delete/merge, schema apply) opens
the engine via a new `open_local_db_with_policy(uri, &config)` helper
that installs the configured `PolicyEngine` when `policy.file` is set,
and threads the resolved actor through to the `_as` writer methods.
Actor identity resolution:
- New top-level `--as <ACTOR>` global flag on the CLI overrides config.
- New `cli.actor` field in `omnigraph.yaml` provides a default actor.
- Precedence: `--as` > `cli.actor` > None.
- When policy is configured and neither is set, the engine-layer
footgun guard fires and the write is denied — silent bypass via
"I forgot the actor" is exactly what the guard prevents.
- Remote HTTP writes ignore both — bearer-token-resolved server-side.
Helpers added in main.rs:
- `open_local_db_with_policy(uri, &config) -> Result<Omnigraph>` —
opens the DB and installs the PolicyEngine when configured. Without
policy this is identical to a bare `Omnigraph::open`.
- `resolve_cli_actor(cli_as, &config) -> Option<&str>` — implements
the flag > config > None precedence.
Engine: added `load_file_as` to the loader as the actor-aware mirror of
`load_file`, so CLI file-path loads flow through the same enforce gate
as in-memory `load_as` calls.
Test rewrite: `local_cli_policy_tooling_is_end_to_end_while_local_writes_stay_unenforced`
was the explicit assertion of the pre-chassis hole. Renamed and split:
- `local_cli_policy_tooling_is_end_to_end` — sanity for the read-only
policy CLI surfaces (validate/test/explain), unchanged behavior.
- `local_cli_change_enforces_engine_layer_policy` — the new assertion:
policy installed + no actor → footgun-guard denial; `--as act-bruno`
on protected main → Cedar denial; `--as act-ragnor` (admins-write
rule) on main → permit, write committed.
POLICY_E2E_YAML gains an `admins-write` rule so the permit case has
a non-trivial actor to exercise.
docs/user/policy.md updated with `cli.actor` + `--as <ACTOR>` usage.

OmniGraph is OSS; internal Linear ticket references and code-review-bot
mentions in source-code comments don't help external readers and leak
internal tooling. Replace ticket numbers (MR-XXX) with descriptive
prose, drop linear.app URLs, and remove inline mentions of
Cursor/Bugbot/Cubic/Codex review threads.
Scope is limited to source-code comments (`crates/`). Docs under
`docs/` keep their MR-XXX references — those are part of the
established change-history narrative for in-repo docs and don't
require a Linear account to find context for.
No behavior changes; no public API changes.

mutate_as and load now write directly to target tables and call the
publisher once at the end with per-table expected versions; the Run
state machine, _graph_runs.lance writers, __run__ staging branches,
and server /runs/* endpoints are removed. Multi-statement mutations
remain atomic at the manifest level via an in-memory MutationStaging
accumulator that gives read-your-writes within a query and a single
publish at the end. Concurrent-writer conflicts surface as
ExpectedVersionMismatch (HTTP 409 manifest_conflict) instead of the
old DivergentUpdate merge shape. Documents one known limitation in
docs/runs.md: a multi-statement mid-query failure where op-N writes
a Lance fragment and op-N+1 fails leaves Lance HEAD ahead of the
manifest until a follow-up introduces per-table Lance branches.
