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.

# Developer Docs
**Audience:** contributors, maintainers, and coding agents
This is the contributor-facing entry point. These docs explain architecture,
invariants, implementation contracts, test ownership, and upstream Lance
constraints. User-facing behavior should still be documented through
[docs/user/index.md](../user/index.md) and the relevant public reference docs.
## Required For Every Non-Trivial Change
| Need | Read |
|---|---|
| Architectural rules, known gaps, deny-list | [invariants.md](invariants.md) |
| Upstream Lance source-of-truth index | [lance.md](lance.md) |
| Existing test coverage and test placement | [testing.md](testing.md) |
## Architecture And Storage
| Area | Read |
|---|---|
| System structure, L1/L2 framing, component diagrams | [architecture.md](architecture.md) |
| On-disk layout, manifest schema, URI behavior | [storage.md](../user/concepts/storage.md) |
| Direct-publish writes, D2, staged writes, recovery sidecars | [writes.md](writes.md) |
| Query execution, mutation execution, loader flow | [execution.md](execution.md) |
| Index lifecycle and graph topology indexes | [indexes.md](../user/search/indexes.md) |
| Branch and commit internals | [branches-commits.md](../user/branching/index.md) |
| Three-way merge implementation and conflicts | [merge.md](merge.md) |
| Diff/change-feed implementation | [changes.md](../user/branching/changes.md) |
| Branch protection policy | [branch-protection.md](branch-protection.md) |
| CODEOWNERS source of truth | [codeowners.md](codeowners.md) |
## Language, Runtime, And Boundaries
| Area | Read |
|---|---|
| Schema grammar, catalog, migration planner | [schema-language.md](../user/schema/index.md) |
| Query grammar, IR, lints, mutation restrictions | [query-language.md](../user/queries/index.md) |
| Embedding client and `@embed` integration | [embeddings.md](../user/search/embeddings.md) |
| Cedar policy surface and server gating | [policy.md](../user/operations/policy.md) |
| Server auth, OpenAPI, endpoint handlers | [server.md](../user/operations/server.md) |
| Error taxonomy and serialization | [errors.md](../user/operations/errors.md) |
| Constants and tunables | [constants.md](../user/reference/constants.md) |
| Transaction model public contract | [transactions.md](../user/branching/transactions.md) |
## Project Operations
| Area | Read |
|---|---|
| CI and release workflows | [ci.md](ci.md) |
| Install and deployment packaging | [install.md](../user/install.md), [deployment.md](../user/deployment.md) |
| Release history | [releases/](../releases/) |
## Contribution & Governance
| Area | Read |
|---|---|
| How to contribute (external) | [CONTRIBUTING.md](../../CONTRIBUTING.md) |
| Governance model, roles, decision authority | [GOVERNANCE.md](../../GOVERNANCE.md) |
| Public contribution RFC track | [rfcs/](../rfcs/) |
The `docs/rfcs/` track is the **public, externally-authorable** RFC process. The
maintainer/internal RFCs below (`rfc-00N-*.md`) are a separate, team-owned
track; don't conflate the two.
## Active Implementation Plans
Working documents for in-flight feature work. Removed when the work lands.

## Boundary
Developer docs may mention implementation details, stale gaps, upstream Lance
blockers, and review rules. User docs should not require that context unless
the detail changes the public contract.
