feat: add configuration for model, mode, and thought level (#205)

* feat: add configuration for model, mode, and thought level

* docs: document Claude effort-level filesystem config

* fix: prevent panic on empty modes/thoughtLevels in parse_agent_config

Use `.first()` with safe fallback instead of direct `[0]` index access,
which would panic if the Vec is empty and no default is set.

* fix: harden session lifecycle and align cli.mdx example with claude.json

- destroySession: wrap session/cancel RPC in try/catch so local cleanup
  always succeeds even when the agent is unreachable
- createSession/resumeOrCreateSession: clean up the remote session if
  post-creation config calls (setMode/setModel/setThoughtLevel) fail,
  preventing leaked orphan sessions
- cli.mdx: fix example output to match current claude.json (model name,
  model order, and populated modes)

* fix: harden session lifecycle and align config persistence logic

- resumeOrCreateSession: Remove destroy-on-error for the resume path. Config
  errors now propagate without destroying a pre-existing session. The destroy
  pattern remains in createSession (where the session is newly created and has
  no prior state to preserve).

- setSessionMode fallback: When session/set_mode returns -32601 and the
  fallback uses session/set_config_option, now keep modes.currentModeId
  in sync with the updated currentValue. Prevents stale cached state in
  getModes() when the fallback path is used.

- persistSessionStateFromMethod: Re-read the record from persistence instead
  of using a stale pre-await snapshot. Prevents race conditions where
  concurrent session/update events (processed by persistSessionStateFromEvent)
  are silently overwritten by optimistic updates.

* fix: correct doc examples with valid Codex modes and update stable API list

- Replace invalid Codex mode values ("plan", "build") with valid ones
  ("auto", "full-access") in agent-sessions.mdx and sdk-overview.mdx
- Update CLAUDE.md stable method enumerations to include new session
  config methods (setSessionMode, setSessionModel, etc.)

* fix: add OpenAPI annotations for process endpoints and fix config persistence race

Add summary/description to all process management endpoint specs and the
not_found error type. Fix hydrateSessionConfigOptions to re-read from
persistence after the network call, and sync mode-category configOptions
on session/update current_mode_update events.

- Regenerate `docs/openapi.json` when HTTP contracts change.
- Keep `docs/inspector.mdx` and `docs/sdks/typescript.mdx` aligned with implementation.
- Append blockers/decisions to `research/acp/friction.md` during ACP work.
- `docs/agent-capabilities.mdx` lists models/modes/thought levels per agent. Update it when adding a new agent or changing `fallback_config_options`. If its "Last updated" date is >2 weeks old, re-run `cd scripts/agent-configs && npx tsx dump.ts` and update the doc to match. Source data: `scripts/agent-configs/resources/*.json` and hardcoded entries in `server/packages/sandbox-agent/src/router/support.rs` (`fallback_config_options`).
- Some agent models are gated by subscription (e.g. Claude `opus`). The live report only shows models available to the current credentials. The static doc and JSON resource files should list all known models regardless of subscription tier.
- TypeScript SDK tests should run against a real running server/runtime over real `/v1` HTTP APIs, typically using the real `mock` agent for deterministic behavior.
- Do not use Vitest fetch/transport mocks to simulate server functionality in TypeScript SDK tests.
