refactor: complete ocw→tj/tokenjam naming migration

[anshss]

Summary

• Sweeps all remaining ocw CLI references across 52 files — docs, examples, incidents, tests, and source
• Renames Prometheus metric prefix ocw_* → tj_* in tokenjam/api/routes/metrics.py
• Updates TypeScript SDK OTel attribute namespace ocw.* → tokenjam.* and default service name ocw-ts-sdk → tj-ts-sdk
• Updates Python import paths from ocw.sdk.* → from tokenjam.sdk.* in all examples
• Updates config/path references (ocw.toml → tj.toml, ~/.ocw/ → ~/.tj/) in docs

Test plan

• pytest tests/unit/ tests/synthetic/ tests/agents/ tests/integration/ — all 293 tests pass
• cd sdk-ts && npm test — TypeScript SDK tests pass with updated semconv assertions
• ruff check tokenjam/ — no lint errors introduced
• Grep for remaining ocw refs (excluding intentional guard in CLAUDE.md): git grep -i '\bocw\b' -- ':!CLAUDE.md'

Reviewed the diff against the working tree. Two real bugs and a fair amount of cleanup

grep -i '\bocw\b' -- ':!CLAUDE.md' still returns 117 matches across 47 files.

Bugs (blocking)

1. UI auth is broken when auth.api_key is set.

tokenjam/api/app.py:92 injects <meta name="tj-api-key" …>
tokenjam/ui/index.html:530 reads meta[name="ocw-api-key"]
Result: API_KEY is null, no Authorization header, every /api/v1/* call 401s.

2. make lint / make typecheck / make all are broken.

Makefile:13 → ruff check ocw/, Makefile:16 → mypy ocw/. Directory is tokenjam/. Both exit 1.
CI passes because .github/workflows/ci.yml runs the commands directly against tokenjam/, bypassing Make.

User-visible strings still saying OCW

UI alerts empty-state — tokenjam/ui/index.html:978 tells users to configure .ocw/config.toml (should be tj.toml).
TS SDK error messages — sdk-ts/src/client.ts:219,231 throw OCW ingest failed: …. Also stale doc-comments at client.ts:2,10, client.test.ts:10, types.ts:2.
Onboard output — cmd_onboard.py:465 ("OCW config:"), cmd_onboard.py:478 ("Codex can now call OCW tools…").
Uninstall output — cmd_uninstall.py:18,21,95,114,153 ("OCW data", "OCW env vars", "OCW env block from .zshrc").
Demo header — cmd_demo.py:72 ("OCW Agent Incident Library").
MCP tool docstrings — tokenjam/mcp/server.py:31,747,870,1037,1040,1059. These get injected into Claude Code's tool list verbatim.

Nits

.gitignore still ignores ocw.toml / .ocw/ only — add tj.toml and .tj/.
Stale local variable names — cmd_uninstall.py:84 (local_ocw = Path(".tj")), nemoclaw.py:88 (ocw_event).
Internal comments / log strings — bootstrap.py:60,74, cmd_mcp.py:57, cmd_onboard.py:220,349,663, mcp/server.py:1. Low priority but easy.
Docs / examples / incidents — README.md, all of docs/, examples/README.md, most examples/.py, all four incidents/* dirs are still OCW-branded. Either include them and earn the "complete" title, or rescope the PR to source + TS SDK and cut a follow-up.
