Pool anon scorer bullets from accomplishment sections (retire rawText walk + buildSkillsExclusion)

[s-annam]

Follow-up from the #127 segmentation spike (docs/segmentation-spike.md), under epic #109. PR 2 — depends on the SectionedResume proof PR (Follow-up A).

Goal

Source the anonymous scorer's experience-bullet pool from the accomplishment sections (experience + projects + achievements) via SectionedResume, instead of walking all of rawText and subtracting skills.

Why

extractBulletsFromText (score.ts:612) walks the whole document and treats every marker-led line as an experience bullet, then subtracts skills via the (now-retired) side-channel. That "pool everything, subtract" shape is the structural reason #30 needed a side-channel at all (spike §1.6). Pooling directly from the accomplishment sections is what the authed scorer already does per-role (score.ts:284-:289); this aligns the two surfaces and removes the last raw-text re-derivation.

Scope

• extractBulletsFromText (or its replacement) iterates input.sections.accomplishmentSections lines rather than rawText.
• Retire buildSkillsExclusion (score.ts:583) and the excludeStripped param — skills lines are simply never in the pool.
• Also retire the scorer's || bullets.length > 0 experience-completeness fallback (score.ts:698) in favor of "is there a non-empty experience section?" (spike §1.5).
• Keep the LONE_BULLET_RE Word-table merge (score.ts:564) but run it within the experience section.

Acceptance

• This is a deliberate scoring change. Bump ATS_SCORE_ALGO_VERSION (score.ts:54) with a changelog entry.
• Corpus goldens regenerated AND spot-audited fixture-by-fixture (don't blind-regen — corpus-snapshot lesson). Document which fixtures moved and why.
• typecheck + corpus suite green.

Implementation Complete — 65864d4

Shipped as PR #139 (stacked on #138 / branch refactor-137-132-fallow-sectioned; merge after #138, then GitHub retargets to main).

Acceptance Criteria

• Pool sourced from accomplishment sections — extractBulletsFromSections iterates input.sections.accomplishmentSections (experience/projects/achievements) via byName, replacing the rawText walk.
• buildSkillsExclusion + excludeStripped retired — skills are excluded by construction (not an accomplishment section). Dead stripBulletMarker also removed.
• Experience-completeness || bullets.length > 0 fallback retired — now expEntries.length > 0 || (sections.byName.get("experience")?.length ?? 0) > 0 (spike §1.5).
• LONE_BULLET_RE Word-table merge kept — runs within each section's line array, not document-wide.
• ATS_SCORE_ALGO_VERSION bumped — 1.2 → 1.3 with changelog entry.
• Corpus goldens regenerated AND spot-audited fixture-by-fixture — 19/24 version-stamp-only; 5 moved, all narrowing (no count increased). Movement table below.
• typecheck + corpus suite green — npm run typecheck clean; npm run test 616 passed (41 files); eslint clean.

Additional Changes

• Edit → re-lint: make parse overrides authoritative (or honest) #82 live bullet-edit re-grade kept working (beyond stated scope, user-approved): applyOverrides gains a sections param + replaceBulletInSections, returns the edited SectionedResume; App.tsx threads it into the scorer. Without this, the pool source change would silently freeze Specificity/Structure on bullet edits.
• rawText retained on AnonymousAtsScoreInput (used only by REDACTED_DATE_RE); docstrings updated.
