Support multiple cwd filters for thread list (#18502)

## Summary

- Teach app-server `thread/list` to accept either a single `cwd` or an
array of cwd filters, returning threads whose recorded session cwd
matches any requested path
- Add `useStateDbOnly` as an explicit opt-in fast path for callers that
want to answer `thread/list` from SQLite without scanning JSONL rollout
files
- Preserve backwards compatibility: by default, `thread/list` still
scans JSONL rollouts and repairs SQLite state
- Wire the new cwd array and SQLite-only options through app-server,
local/remote thread-store, rollout listing, generated TypeScript/schema
fixtures, proto output, and docs

## Test Plan

- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-rollout`
- `cargo test -p codex-thread-store`
- `cargo test -p codex-app-server thread_list`
- `just fmt`
- `just fix -p codex-app-server-protocol -p codex-rollout -p
codex-thread-store -p codex-app-server`
- `cargo build -p codex-cli --bin codex`
