test(miner-plan): add prompt-packet builder and adversarial redaction suite (#2321)

[andriypolanski]

Summary

• Add packages/gittensory-engine/src/prompt-packet.ts — metadata-only analyze-phase prompt-packet builder (four text fields) with redaction/allowlist filtering over the canonical PUBLIC_UNSAFE_TERMS and PUBLIC_LOCAL_PATH_INLINE vocabulary.
• Add test/unit/prompt-packet-redaction.test.ts — 93 parametrized adversarial tests: every unsafe-term family and local-path prefix (parsed from the regex sources, not hand-copied), injected into each packet field; double-jeopardy; byte-identical clean pass-through.
• Export the builder from @jsonbored/gittensory-engine barrel.

Closes #2321

Scope

• Parametrized over every term family in PUBLIC_UNSAFE_TERMS × four packet fields
• Local-path injection for every prefix in PUBLIC_LOCAL_PATH_INLINE × four fields
• Double jeopardy (unsafe term + local path in the same field)
• Clean fields byte-identical after buildPromptPacket
• Builder prerequisite included — prompt-packet.ts was not on main yet

Review summary
This PR adds a new metadata-only prompt-packet builder (`prompt-packet.ts`) with regex-based redaction of unsafe economic/identity terms and local filesystem paths, plus a genuinely rigorous 93-case adversarial test suite that parses the canonical `PUBLIC_UNSAFE_TERMS`/`PUBLIC_LOCAL_PATH_INLINE` alternation sources (from `src/signals/redaction.ts`) rather than hand-copying terms, so drift between the canonical vocabulary and the duplicated copy in `prompt-packet.ts` would break tests. The core redaction logic (local-path scrub before term scrub, double-jeopardy handling, byte-identical clean pass-through) checks out correctly against the enumerated test cases and the regexes shown. The diff also bundles unrelated timeout bumps (`, 60_000`) into three pre-existing tests in `test/unit/queue.test.ts` and `test/unit/rag-wiring.test.ts` that aren't mentioned in the PR's 'Changed files' table.

Nits — 4 non-blocking

• The vocabulary in `prompt-packet.ts:3-5` is a hand-duplicated copy of `PUBLIC_UNSAFE_TERMS`/`PUBLIC_LOCAL_PATH_INLINE` from `src/signals/redaction.ts` rather than an import — the code comment acknowledges this is intentional for standalone-package reasons, and the test suite does detect drift by parsing the canonical source, but this is still a manual-sync burden worth a follow-up (e.g. a build-time equality assertion between the two constants) rather than relying solely on the test suite to catch divergence.
• The timeout bumps to `queue.test.ts:7245` and `queue.test.ts:7290` and `rag-wiring.test.ts:416` are undisclosed scope creep — the PR description's 'Changed files' table only lists the three prompt-packet files, not these pre-existing test timeout changes; call out why these were needed (flaky CI timeout?) in the description.
• Consider a small unit test (or a lint/build step) asserting `PUBLIC_UNSAFE_TERMS`/`PUBLIC_LOCAL_PATH_INLINE` string literals in `prompt-packet.ts` are byte-identical to the ones exported from `src/signals/redaction.ts`, so drift fails fast instead of only failing indirectly through redaction-behavior test mismatches.
• Fold the queue.test.ts/rag-wiring.test.ts timeout changes into the PR description's changed-files table, or split them into a separate PR if they address a different (flaky-CI) concern than test(miner-plan): adversarial redaction/allowlist test suite for the prompt-packet builder #2321.
