docs: address Copilot review round 1 on #2203

Fixes an unquoted `#` in `board-ops`'s description. YAML reads ` #28`
onward as a comment, so the parser — and Claude Code, which parses the
same way — only ever saw the description up to `Covers board`. Both
board numbers and the option-deletion hazard were absent from the
listing that decides whether the skill fires, and every check stayed
green because they look for an *empty* description and a truncated one
is still non-empty. Quoting restores all 271 characters, which is the
whole of the 3,144 vs 3,234 discrepancy the review flagged.

`parseSkill` now compares the raw scalar against what YAML kept and
errors on any loss, so the next one fails the gate rather than shipping.
Tests cover the truncated case and a legitimately quoted `#`.

Re-aims the `project-structure` Node-backend case, which `AGENTS.md`
answers via its tree and which had oscillated 80 -> 100% across runs —
the partial-overlap signature this PR documents. The replacement names
no internals and probed 4/4.

Makes the documented probe reproduce the harness: the same
`--disallowedTools` flags as `runPrompt` rather than `--allowedTools`,
`printf` instead of zsh's `print -r`, and `jq` over `tool_use` blocks
instead of a `grep` that also matched MCP server names in the init
event. The first-tool-call table is relabelled as an unrestricted probe,
since the eval cannot reach for Bash at all.

RUNS=5 skills:eval: 63/63, 62 at 100%; restoring those 90 characters
displaced nothing.
