docs(rfc-002): rewrite config & CLI architecture + readiness review
Rewrite RFC-002 around a typed GraphLocator (storage: XOR server:+graph_id:),
servers:+graphs: with three-tier addressing, serve: vs servers: de-collision,
global-first layered config, a method x source auth model, and an
omnigraph-config crate extraction. Verified against code, not ticket status.

Incorporates the implementation-readiness review (10 points):
 1. current flag is --target, not --graph; --graph canonical + --target alias
 2. credential-redirection fix: endpoint-bound creds + layer identity rule + AX threat model
 3. no-arg resolution: defaults.graph for bare commands; defaults.server only namespaces unknown ids
 4. route unification spec: canonical single-mode graph_id; GET /graphs lists served set
 5. serve.graphs replaces server.graph (preserves serve-a-subset)
 6. restore query.roots (ad-hoc --query path resolution)
 7. soften 'structurally unreachable'; move mTLS key off the repo tree
 8. legacy bearer_token_env -> synthesized-server migration
 9. enumeration caveat: known-id addressing vs graph_list-gated discovery
10. mark oauth/mtls reserved; full impl deferred to V6

Also realigns the docs/dev/index.md entry.

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 and the relevant public reference docs.

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.
