CI hygiene: job timeouts, CodeQL matrix fix, drop spurious nuget (#64)

Follow-up to #63, addressing the **pre-existing, repo-wide** CI failures
and Hypatia workflow-audit findings (61) that were unrelated to the
KitchenSpeak elevation but surfaced alongside it. Work was fanned out
across the workflow files in parallel.

## Changes

**`timeout-minutes` (the bulk of the `missing_timeout_minutes`
findings)** — added to every real `runs-on`+`steps` job that lacked one:
- `boj-build` (trigger-boj), `casket-pages` (build, deploy), `codeql`
(analyze), `dogfood-gate` (5 jobs), `instant-sync` (dispatch),
`scorecard-enforcer` (scorecard, check-critical), `semgrep`,
`workflow-linter`.
- ⚠️ **Deliberately not added** to reusable-workflow *caller* jobs
(`governance`, `hypatia-scan`, `mirror`, `scorecard`, `secret-scanner`)
— GitHub Actions **rejects** `timeout-minutes` on a job whose body is
`uses:`, so adding it there would break those workflows. Those findings
are effectively false positives for caller jobs.

**`codeql.yml`** — switch the analysis matrix `javascript-typescript` →
`actions`. The repo has no JS/TS sources, so `analyze` failed *"no
source files"* on every run; `actions` scans the workflow files every
repo has. Fixes the recurring **analyze** failure.

**`dependabot.yml`** — remove the spurious `nuget` ecosystem entry. The
repo has zero .NET projects (verified), which is what underpins the
always-failing **submit-nuget** check. Note: the `submit-nuget` *check*
itself is org-level (`hyperpolymath/.github`), not defined in this repo,
so this removes the local root cause but the org workflow may still need
adjusting.

**`instant-sync.yml`** — fix a **pre-existing YAML error**: a stray
`K9-SVC Validation` step was mis-indented to `jobs:` level, making the
entire workflow invalid YAML (confirmed broken on `main`, not introduced
here). Re-nested it into the `dispatch` job's `steps`. Validated with
PyYAML.

## Validation
All 9 changed files parse cleanly (`yaml.safe_load_all`).

## Not done (needs your hands)
- **One unpinned action**:
`hyperpolymath/standards/.github/workflows/governance-reusable.yml@main`.
I couldn't resolve its SHA from here (the `standards` repo is outside
this session's API scope; the unauthenticated commits API returned 403).
The `governance` check is currently green, so I left `@main` rather than
guess a SHA and risk breaking it. Pin manually:
  ```
gh api
'repos/hyperpolymath/standards/commits?path=.github/workflows/governance-reusable.yml&sha=main&per_page=1'
--jq '.[0].sha'
  ```
  then replace `@main` with `@<sha>  # main` in `governance.yml`.
