fix(validate): support enum-based multi-exit and upgrade json-cas to 0.5.3

Two fixes for 'uwf thread start solve-issue' failures:

1. json-cas 0.5.2 (npm) was missing oneOf in ALLOWED_SCHEMA_KEYS.
   Published json-cas 0.5.3 with the fix, bumped all packages to ^0.5.3.

2. Semantic validator only recognized oneOf-based multi-exit schemas.
   Roles using $status with enum (e.g. enum: [approved, rejected]) were
   incorrectly treated as single-exit. Added isEnumMultiExit() support.

Changes:
- validate-semantic.ts: isEnumMultiExit(), getEnumStatuses(), checkSingleExitMustache()
- All package.json: @uncaged/json-cas ^0.5.2 → ^0.5.3
- validate-semantic.test.ts: 5 new enum multi-exit tests (Suite 3b)
- solve-issue-tea-worktree.test.ts: updated for current workflow structure

-      2. cd to the repoPath before making any changes.
-      3. Create a feature branch from the default branch.
-      4. Implement the plan — write code, tests, and ensure existing tests pass.
-      5. Run the project's lint/check command (e.g. `bun run check`, `npm run lint`) and fix ALL errors before proceeding. Build and lint must pass cleanly.
-      6. Commit your changes with a descriptive message referencing the issue.
-    output: "List all files changed and provide a summary of the implementation."
+      IMPORTANT: Always work in a git worktree, NEVER modify the main working directory directly.
+      The repo path and other details are provided in your task prompt.
+
+      Before starting any work, set up an isolated worktree:
+      1. cd into the repo path provided in your task prompt
+      2. `git fetch origin` to get latest refs
+      3. First time (no existing branch):
+         - `git worktree add .worktrees/fix/<issue-number>-<short-slug> -b fix/<issue-number>-<short-slug> origin/main`
+         - `cd .worktrees/fix/<issue-number>-<short-slug> && bun install`
+      4. If bounced back from reviewer or tester (branch already exists):
+         - cd into the existing worktree under `.worktrees/fix/<issue-number>-<short-slug>`
+         - `git fetch origin && git rebase origin/main`
+      5. ALL subsequent work must happen inside the worktree directory.
+
+      Then implement TDD:
+      6. Read the test spec from CAS: `uwf cas get <plan hash>` (find the hash from the planner's output in your task prompt)
+      7. If bounced back from reviewer or tester: read the previous role's feedback in your task prompt
+      8. Write tests first based on the spec
+      9. Implement the code to make tests pass
+      10. Ensure `bun run build` passes with no errors
+      11. Run `bun test` to verify all tests pass
+
+      If you cannot complete the implementation (e.g. the issue is too complex, blocked by external factors,
+      or repeated attempts fail), set $status=failed with a reason.

 Layer 3 agent implementation. Wraps the Hermes CLI using the Agent Client Protocol (ACP). On first visit to a role it sends a composed prompt (role definition, task, history, edge prompt); on continuation it resumes the cached session. Session transcripts and raw output are stored as CAS detail nodes.
