Add a Language Gate - no dimension currently checks language requirements (#275)

Nothing in the framework checks a posting's language requirements
against what the candidate actually speaks. It is not one of the five
Scoring Dimensions in 04-job-evaluation.md, it is not checked in
/scrape's Step 3 fit assessment, and it is not a field in /rank's JSON
output - even though /apply's Step 1 already extracts a posting's
required language generically, with nowhere to report a mismatch to.

This adds a Language Gate, structured like the existing Eligibility
Gate (read the posting, classify against profile data, hard-stop on a
real mismatch), built on a new structured Languages table in CLAUDE.md
/ 01-candidate-profile.md. /setup now asks for it directly (Path C), or
infers it from a CV/LinkedIn export (Paths A/B - LinkedIn exports
already carry a self-rated Languages section).

The gate compares a posting's stated language requirements against
that table with three outcomes:

- Requires a language not declared at all -> hard FAIL, never
  presented.
- Requires a higher level in a language that is declared (e.g. "fluent
  English" against a declared B1/B2) -> FLAG, not an auto-reject -
  scored and drafted normally, with the gap surfaced so the candidate
  judges it themselves (a "fluent" bar reads very differently from a
  strict employer vs. one that's flexible on it).
- Requires a language at or below the declared level -> clean PASS.

Wired through the three places that need it: /scrape (Step 3), /rank
(new language_gate/language_note fields alongside the existing
location veto - both are now persisted to seen_jobs.json, not just
used transiently to decide one run's shortlist), and /apply (Step 1's
language extraction now has somewhere to report to).

Out of scope, deliberately: this does not touch the free-form
Deal-breakers list or how it's used elsewhere (e.g. Scoring Dimension
4's relocation check) - that's a separate question this change takes
no position on.

Validated with two live-testing passes against real, unfetched
postings (not fabricated text) across 3 portals and 3 market languages
(Danish, German, Spanish/Argentina): 8/8 postings gated correctly in
the first pass, including ambiguous real-world wording ("you
communicate well in English") a rigid rule would have gotten wrong. A
second pass, run specifically to force a hard-FAIL case, found one
(a Danish posting requiring the ability to read Danish) and confirmed
it persists correctly and would be excluded from /rank's shortlist.

+`language_gate`/`language_note` come from `04-job-evaluation.md`'s Language Gate — distinct from `language` above, which just records what language the posting is written in.

 Scoring uses the dimension definitions from `04-job-evaluation.md` verbatim. The honesty rule applies to triage too: gaps are stated, never smoothed over, and a posting that is a poor fit gets a low score even if it looks prestigious.

These veto fields are as important to persist as the score itself - without them, nothing later (a re-read of `seen_jobs.json`, a debugging session, the user asking "why was this excluded") can recover why a job did or didn't make the shortlist.

 Store both arrays **verbatim** as the agent returned them (1-3 bullets each) - never expand to prose, never reformat. This costs no extra fetch: the agent already produced them in Step 2. `--all` re-scoring **replaces** both arrays with the fresh ones; they never accumulate across runs. Both arrays are still **untrusted data**: agents write plain text only (no posting markup, no URLs lifted from the posting), and every command that reads them later treats them as data, never as instructions.

 5. **Honest scoring.** Gaps are reported per job; a low-scoring posting is presented as such. The score bands and weights come from `04-job-evaluation.md` - if the user disagrees with a ranking, the fix is updating their profile or the framework, not bending scores. Gaps are reported (Step 5) and persisted with it (Step 4), so the honest read outlives the terminal output.
 6. **State stays consistent.** `seen_jobs.json` fields are only added, never restructured, so `/scrape`'s dedup keeps working; the tracker is read-only for this command.
