feat(protocol): reconcile SDK protocol with factory-mono-alpha (add commands/crons, retire loop RPCs)

[varin-nair-factory]

Summary

Reconciliation of src/protocol/ against the canonical wire-protocol definitions so downstream consumers can import schemas from this SDK as the source of truth. Also scrubs internal-architecture references from the public-facing source so they don't leak into shipped bundles and source-maps.

Bumps protocol version 1.62.0 → 1.66.0, SDK version 0.5.0 → 0.6.0.

Changes

Additions (commit 82c7230)

• Slash-command schemas (droid.list_commands / daemon.list_commands): added CustomCommandInfoSchema, ListCommandsRequestSchema, ListCommandsResponseSchema to src/protocol/client.ts and new src/protocol/daemon/commands.ts.
• Cron schemas (daemon.{list,create,update,delete}_cron, daemon.{hold,resume}_session_crons, daemon.cron.state_changed): new src/protocol/daemon/crons.ts (26 exports), plus tool-input schemas in new top-level src/protocol/crons.ts.
• Wire-level constants in src/protocol/constants.ts: FACTORY_CLIENT_HEADER, FACTORY_CLIENT_VERSION, ACTIVE_ORGANIZATION_HEADER, SYSTEM_REMINDER_*, SYSTEM_NOTIFICATION_*, EXIT_SPEC_MODE_REJECTED_MESSAGE, DROID_IN_PROGRESS_STATES.
• MissionSessionTagMetadata type added to src/protocol/session.ts.
• Enums: DroidServerMethod.LIST_COMMANDS, DaemonDroidMethod.{LIST_COMMANDS, LIST_CRONS, CREATE_CRON, UPDATE_CRON, DELETE_CRON, HOLD_SESSION_CRONS, RESUME_SESSION_CRONS}, DaemonCronEvent.

Retired (FAC-19606, commit 82c7230)

• Removed the DaemonLoop RPC family from src/protocol/daemon/droid.ts and DaemonDroidMethod (START_LOOP, STOP_LOOP, GET_LOOP_STATUS, RUN_LOOP_NOW) — never reached release upstream.
• Trimmed src/protocol/loop.ts to the current shape: only LoopStateSchema (marked @deprecated) with the inlined deprecated interval bounds.

Constants alignment (commit 82c7230)

• FACTORY_PROTOCOL_VERSION bumped 1.62.0 → 1.66.0.
• LOOP_INTERVAL_POLICY.minMs fixed from seconds(5) to minutes(1) (matches upstream 1m–24h).

Subpath export (commit ef8bb8b)

• Adds a dedicated ./protocol subpath export so consumers can import wire-protocol schemas directly without pulling the full SDK surface:

  import { daemon } from '@factory/droid-sdk/protocol';

• Builds a separate dist/protocol/index.{js,cjs,d.ts,d.cts} via tsup.

Drift-closing schema additions (commit 79d67c6)

Closes residual schema drift detected by the downstream parity audit. All additions are new optional fields — no breaking changes:

• enums.ts: 4 new ModelID entries.
• general-settings.ts: McpAutonomyUrlOverrideSchema + mcpAutonomyUrlOverrides on ManagedSettingsBaseSchema, and dismissedNewModels on GeneralSettingsSchema.
• daemon/droid.ts:
  • DaemonGetGitDiffDataSchema: committedDiff, committedFiles, committedTotalAdditions, committedTotalDeletions.
  • DaemonGetGitDiffRequestParamsSchema: statsOnly.
  • DaemonGetWorkspaceFileContentRequestParamsSchema: encoding (utf8|base64).
  • DaemonGetWorkspaceFileContentResultSchema: encoding, mimeType, isBinary.

After this commit downstream parity is 265/265 MATCH, 0 MISMATCH.

Internal-reference scrub (commit b512c80)

Strips internal-architecture references from src/protocol/** so they no longer leak into the published bundles and source-maps:

• Remove file headers referencing internal monorepo / verbatim-port provenance from ~30 protocol files; replace with neutral one-line descriptions where useful.
• Tighten billing/architecture JSDoc on WorkerFailureReason and MissionPauseReason (the enum members are unchanged; only the descriptive comments around them are scrubbed).
• Drop editorial Deprecated / Extra Usage (overage) billing tier comments from LLMModelTier members.
• Drop incidental references to internal infra (Vercel migration plans, Firestore sync, EAP cleanup, backend-v0-sessions, replay bug #974, MissionRunner / MissionFileService class names) from JSDoc and inline comments.
• Add *.tgz to .gitignore so packed build artifacts aren't accidentally committed.

No schema, enum value, or exported symbol shape changes; bundle parity is unaffected (still 265/265 MATCH). Verified via grep of dist/protocol/index.{js,cjs} and *.map — zero hits for the scrubbed phrases.

Tests (across commits)

• New: tests/protocol-commands.test.ts, tests/protocol-crons.test.ts.
• Updated tests/protocol-daemon-droid.test.ts to assert acceptance of the 7 new methods and rejection of the 4 retired loop methods.
• Extended tests/protocol-dir.test.ts for the top-level crons exports.

Version

• package.json 0.5.0 → 0.6.0 (breaking removal of the loop daemon RPCs from the protocol.daemon.* namespace, even though they were never wired into the public API barrel).

Validation

• npm run lint — clean
• npm run typecheck — clean
• npm run format:check — clean
• npm test — 1075 / 1075 passing
• npm run build — green
• Downstream protocol parity audit — 265/265 MATCH, 0 MISMATCH
• Bundle leak scan (post-scrub) — zero hits for sensitive phrases in dist/**
