chore(release): prepare v0.9.7

Release prep for v0.9.7:
- Bump the workspace, per-crate pins, npm wrapper, and lockfile to 0.9.7.
- Finalize the [0.9.7] CHANGELOG entry: Grok 4.6 as the ordinary catalog
  default, OrcaRouter as a named provider, the session snapshot/recovery
  split, canonical message copy, and the RUSTSEC-2026-0253 lru/ratatui-core
  fix. All factual claims in the entry were checked against the code.
- Document the known parallel-load flake
  exec_persistent_service::failed_exec_kills_pending_service_and_exits_nonzero
  ("service pid file never appeared"); it passes in isolation and is
  unrelated to any v0.9.7 change.
- Regenerate the TUI changelog slice and web/lib/facts.generated.ts.

Gates run on this tree: cargo fmt/check/clippy clean; the full workspace
suite completed with --no-fail-fast and exactly one failure (the documented
flake, passing in isolation); publish-crates.sh dry-run and the npm wrapper
smoke passed; the release binary reports 0.9.7 and `codewhale model resolve
grok` resolves grok-4.6 on provider xai.

Release preparation assisted by CodeWhale, following docs/RELEASE_CHECKLIST.md.
