fix(ci): stop blocking Bun — it is tier 1, not an anti-pattern (#196)

`npm-bun-blocker.yml` **failed the build when a Bun lockfile was
present** — while the owner's 2026-08-26 ruling makes Bun **tier 1** and
the corrected policy says `package.json` + `bun.lock` are *"expected,
not anti-patterns"* (standards#655).

So the workflow rejected exactly what the policy mandates. **40 copies
updated here**; they now reject npm/pnpm/yarn lockfiles only.
Estate-wide the pattern was in **272 of 273 copies across 34 repos**.

Also repairs blanked tokens from the language purge (*"Use instead."* —
the tool name substituted with an empty string) and stale *"Use Deno
instead"* text.

## Verification

Every edited file was re-parsed with `yq`; any edit that would have
produced invalid YAML was **reverted automatically**. The repo-wide
count of unparseable workflows is **unchanged at 39** before and after.

## ⚠ Found, not fixed — 39 workflows here do not parse at all

Of this repo's **1,739** workflows, **39 fail to load**, so they have
never run. One was diagnosed:


`rescript-ecosystem/packages/tooling/evangeliser/.github/workflows/npm-bun-blocker.yml`
contains a literal **backspace byte (0x08)** inside a regex:

```
grep -E '^\+.*<BS>(npm|bun)\s+(run|install|start|test|build)'
```

YAML rejects control characters, so the file never loads and the blocker
it implements **has never executed**. Removing the byte exposes a
further structural error at lines 21–22, so it needs authoring rather
than a one-character fix.

It is left **exactly as found** — not half-repaired — and excluded from
this change.
