fix(map): the Code map gate's fixtures and history, and the one-time pin bootstrap

[cryptskii]

Main's Code map check has been red since #1057 merged. It was merged before its last two steps, and this PR is those two steps.

What was red on main (run 36556460780, at 8b28149)

• The evidence pins refuse what they must. Two causes:
  • .gitignore's *.log silently kept the four board-log fixtures out of feat(map): Stage 2, evidence pins and an always-run merge gate #1057, so they existed only on the capturing machine.
  • The Code map job's checkout was shallow, while the pins' tests read a commit's parent and the repository's first commit.
• The intent manifest holds against the map. It reported "pins: not checked: specs/requirements/INTENT_PINS.tsv does not exist". The pins had not been bootstrapped yet.

The same run's Pin evidence job passed. With nothing pinned, it ran every requirement row's evidence tests on 8b28149, 289 distinct tests in 18 cargo runs, and every one passed. Its log and the run's code-map artifact are what the bootstrap below pins from.

Commits

1. fix(ci): commit the board-log fixtures, and give the pins' tests history.
   • A .gitignore negation now tracks exactly ci/fixtures/board-logs/*.log.
   • The Code map job's checkout now uses fetch-depth: 0.
2. feat(map): the one-time pin bootstrap.
   • ci/intent_pins.py pin-unpinned wrote 561 pins, one per requirement row with known holes included, all at 8b28149.
   • Before writing, it checked that:
     • this tree's compiled code is 8b28149's;
     • CI's map fingerprints as this tree;
     • the map indexed every build;
     • every evidence test resolves to one definition and passed in CI's log.

Verified against CI's map (android and node indexed)

• The intent manifest reads 1,074 rows, 0 failing and 6 known holes.

• The pins read 561/561 PINNED.

• ci/test_intent_pins.py passes 14/14.

• Live on the real pins, both edits restored afterwards:

  • a CONFORMANCE §8 status edit (MR-STOR-0146 Met → Partial) stales both its pins under status;
  • a manifest citation edit stales its pin under citation.

  The first is the markdown-only change the old path filter skipped.

On this PR's CI

• Code map rebuilds the map on this commit. The pins file is not a map input, so its facts are unchanged and every pin should read PINNED.
• Pin evidence sees all 561 pins as new against main and reruns their evidence on this commit: the full proof the bootstrap rests on, run once more.

From here, only pin KEY and repin KEY change a pin, one key at a time. Making Code map a required check waits for the owner's approval.
