omnigraph/docs/errors.md

Refactor AGENTS.md from encyclopedia to map; move spec into docs/
Splits the 990-line AGENTS.md into a 184-line map (architecture,
where-to-find index, always-on invariants, capability matrix,
maintenance contract) plus 18 new docs/*.md files holding the deep
content per topic (storage, schema and query languages, indexes,
embeddings, branches/commits, runs, merge, changes, execution, policy,
server, CLI reference, audit, errors, CI, constants, v0.3.1 notes).

Adds scripts/check-agents-md.sh and a check_agents_md CI job that
verifies every docs/ link in AGENTS.md resolves and every doc in the
canonical set is linked. CLAUDE.md remains a symlink to AGENTS.md.

# Errors and Result Serialization
## Error taxonomy (`omnigraph::error::OmniError`)
- `Compiler(...)` — schema/query parse/typecheck errors
- `Lance(String)` — storage layer
- `DataFusion(String)` — execution layer
- `Io(io::Error)`
- `Manifest(ManifestError { kind: BadRequest|NotFound|Conflict|Internal, … })`
- `MergeConflicts(Vec<MergeConflict>)`
Compiler-side `NanoError` covers parse / catalog / type / plan / execution / arrow / lance / IO / manifest / unique-constraint, each with structured spans (`SourceSpan { start, end }`) for ariadne-style diagnostics.
## Result serialization (`omnigraph_compiler::result::QueryResult`)
- `to_arrow_ipc()` — efficient binary
- `to_sdk_json()` — JS-safe JSON (large i64 wrapped in metadata)
- `to_rust_json()` — Rust-friendly JSON
- `batches()` — direct Arrow `RecordBatch` access
Mutation results: `{ affectedNodes: usize, affectedEdges: usize }` (also exposed as a tiny Arrow batch).
