docs(evaluation): reframe onboarding and matching guidance around function, not title (#330)

Title-lookalike matching collapses a multi-hat career into whichever single
job-title box sounds closest, then searches only inside that box. /setup
Section 9 now asks about the function before collecting search titles,
search-queries.md says to organize priority categories by function with title
variants under each, and 04-job-evaluation.md's Experience dimension matches on
the function and nature of work performed (framework_version 1.2.2 -> 1.2.3).
From discussion #327's field report and calibration example.

 ### Changed
 
+- **Job matching reframed around function, not title** (`framework_version` 1.2.2 -> 1.2.3 in
+  `04-job-evaluation.md`) - title-lookalike matching throws away career capital that doesn't
+  fit one job-title box (e.g. a background spanning research leadership, platform ownership,
+  and program management gets collapsed into whichever single title sounds closest). `/setup`,
+  `search-queries.md`, and `04-job-evaluation.md` now guide the candidate to define priority
+  categories by function - the kind of problem a role solves - and to list several plausible
+  job titles as query variants within each category, rather than betting an entire priority
+  tier on one exact title string.
