docs(user): restructure user docs into topic sections (Phase 1) (#223)
Move the 23 flat docs/user/*.md files into topic subdirectories so the
user guide is organized by area (schema, queries, search, branching, cli,
operations, clusters, concepts, reference) instead of a flat list. This is
a pure structural move — whole files relocated, every cross-doc link
recomputed, no prose rewrites or content splits (those follow in Phase 2).

- 19 `git mv`s (install.md, deployment.md stay top-level); history preserved
  (renames detected at 92–100% similarity).
- All intra-doc links, AGENTS.md's topic table (52 pointers), and the
  docs/dev + docs/releases back-links recomputed via relpath from each
  file's new location.
- docs/user/index.md rewritten as a sectioned nav hub.
- Fixed 5 doc-path references in Rust (comments + two user-facing server
  settings error strings) to point at the new locations.

Verified: zero broken .md links across tracked docs; check-agents-md.sh
green (with the untracked scratch docs set aside); touched crates build.

Note: the public site (omnigraph-web) imports docs/ via a flat-only script;
its import-docs.mjs needs a subdir-aware update before the next re-sync.

Change Detection / Diff

changes/mod.rs. Three-level algorithm:

  1. Manifest diff: skip sub-tables whose (table_version, table_branch) is unchanged.
  2. Lineage check:
    • Same branch lineage → fast path: use the per-row _row_last_updated_at_version column to classify Insert/Update/Delete.
    • Different lineages → ID-based streaming comparison.
  3. Row-level diff: streaming, no full materialization.

Public API

  • diff_between(from: ReadTarget, to: ReadTarget, filter: Option<ChangeFilter>) -> ChangeSet
  • diff_commits(from_commit_id, to_commit_id, filter) — cross-branch safe.

Types

ChangeOp: Insert | Update | Delete
EntityKind: Node | Edge
EntityChange { table_key, kind, type_name, id, op, manifest_version, endpoints?: {src, dst} }
ChangeFilter { kinds?, type_names?, ops? }
ChangeSet { from_version, to_version, branch?, changes[], stats }
