fix(fr): apply French typography deterministically instead of asking the model - #79

* chore: release v0.16.0

- Bump version to 0.16.0
- Promote [Unreleased] changelog to [0.16.0]
- Rebuild dist-action bundle (unchanged — the version is not embedded in it)
- Refresh version/test counts in README + copilot-instructions (1005 → 1056,
  39 → 40 suites)

Changelog accuracy, beyond the promotion:

- The thinking entry described the off default as a hold pending measurement.
  That experiment has since concluded — adaptive thinking self-regulates to
  ~zero on translation (+24-32 tokens even at effort: high), so off is a settled
  decision. Rewritten; shipping release notes that call a settled decision
  provisional would mislead anyone deciding whether to override it.
- Stated plainly that the typography pass added in #79 covers the CLI init path
  ONLY and does not change how the action syncs. Verified rather than asserted:
  `applyTypography` does not appear in dist-action/index.js at all. Without this,
  a maintainer would reasonably assume 0.16 fixed typography for their sync.
- Fixed the 0.15.0 release date: it read 2025-07-14, which is impossible — it
  would predate 0.14.1 (2026-04-09). The tag is dated 2026-04-14.

Also added `typography.ts` and `models.ts` to the architecture.md module tree.
Both were missing (models.ts since #75), so bumping that doc's version stamp
without them would have made it more wrong, not less.

Verified: 1056 tests green, lint clean (0 errors), a fresh `npm run build`
leaves dist-action byte-identical, and action.yml's claude-model default matches
DEFAULT_CLAUDE_MODEL.

* chore: sync package-lock version with package.json

Addresses Copilot's review on #80. Valid, and longer-standing than the PR: the
lockfile still declared 0.8.0, having not been version-bumped since #24 — it
drifted silently through seven releases. A release PR is the right place to stop
that.

No downstream impact today (the package is not published — `npm view` 404s), but
`private` is false, so it could be, and the metadata was simply wrong either way.

Changed the two version fields directly rather than running
`npm install --package-lock-only`, which re-resolves and could churn transitive
dependencies inside a release PR. Diff is exactly 2 lines; `npm ci --dry-run`
accepts the lockfile; build and 1056 tests still green.

Bulk translation of lecture-python-programming into French, seeded with
QuantEcon/action-translation's `translate init`.

- Model: claude-opus-4-8. Opus is used for one-time seeds because it showed zero
  cross-lecture terminology drift over a 5-lecture trial where Sonnet 5 drifted
  on 5 terms, and was correct where Sonnet was not (`mutable`, not `muable`).
  It costs 1.66x, which is worth it once for a corpus a native speaker then
  reviews. Ongoing sync stays on Sonnet 5.
  See QuantEcon/action-translation `.dev/decisions/D-2026-07-14-opus-for-bulk-seed.md`.
- Glossary: 364 terms, including 7 programming-domain terms proposed in
  QuantEcon/action-translation#78 and still under native review.
- French typography (non-breaking space before ; : ! ?) applied deterministically
  rather than via the prompt, which the model ignores. 331 inserted.
  See QuantEcon/action-translation#79.
- 26/26 translated, 687k tokens, 34 minutes.

This is a draft for review, not a finished edition.

…h body (#99)

* fix(sync): apply typography in the sync path, typeset map with body

applyTypography() ran only in the `translate init` seed path, so every sync
stripped the non-breaking spaces the seed inserted and fell back on the prompt
instruction #79 was opened because the model ignores. One merged sync took
numba.md from 27 to 14 non-breaking spaces, invisible in review because the
diff renders as unchanged text.

Both sync entry points now typeset:

- processFull: on the raw model output, before the heading map is derived from
  it — the same ordering as init.ts.
- processSectionBased: on the reconstructed document, before the map is
  injected. Document-scoped, so drift in sections the source PR did not touch
  is repaired on the next sync of that file.

The map is typeset alongside the body rather than after it. applyTypography
skips frontmatter by design, so typesetting already-injected content would
leave map values plain-spaced while body headings gained non-breaking spaces.
Heading lookup is an exact string compare with no whitespace normalisation, and
the positional fallback is unavailable whenever the section count changes, so
that mismatch silently drops unchanged sections and retranslates modified ones
from English, discarding human edits. Body, map, and title are typeset
together, matching what scripts/typography/apply.mjs already did.

Tests were verified to fail against both the unfixed code and the body-only
variant; against the latter the added-section case reports a skipped section,
which is the data loss above.

* fix(review): use the U+00A0 escape in tests, repair CHANGELOG clause

Addresses Copilot feedback on #99.

The test file defined NBSP as a raw literal non-breaking space, the only such
definition in the repo -- src/typography.ts and src/__tests__/typography.test.ts
both spell it as an escape sequence. An invisible character is a poor definition
for the constant every assertion in the suite depends on: an editor could mangle
it silently, and the tests would then compare plain spaces to plain spaces and
pass vacuously. Line 16 held the only literal; every fixture already interpolates
${NBSP}, so fixing the definition covers the file.

Verified the change is a behaviour no-op by re-running the tests against both
broken variants: 7 of 9 still fail against main's file-processor.ts, and 3 of 9
against the body-only variant.

The CHANGELOG clause tried to extract the object of "ignores" out of a
because-clause, which no single missing word repairs. Rewritten to match the
wording used in the issue.
