RSI Phase 2: segmentation-boundary audit task type

[ronshapiro]

Summary

Phase 2 of RSIAgentRedesignPlan.md: the second content-generation task type, and the first genuinely new one under the redesigned architecture (Phase 1, #56, only re-platformed the existing translation task).

• segmentation_audit.ts: for a given page, asks Claude to review Gemara segment and Rashi/Tosafot comment boundaries for coherence issues (e.g. "this Rashi comment is really two comments merged together") using the page skeleton + context_fetch_cli for anything it needs to actually read. Deliberately an audit, not a mutation — it never changes segment boundaries itself; findings are written to precomputed/rsi_state/segmentation_suggestions/<Book Page>.json for a human to review and act on manually (no in-page review UI yet — that's Phase 3).
• No self-critique pass, unlike translation: since nothing here is auto-applied, the human reviewer is the real judgment gate. A cheap local check (no model call) still drops any suggestion referencing a ref that isn't actually on the page, as a guard against a hallucinated ref.
• Staleness is keyed on a boundary fingerprint (the ordered list of segment/comment refs) rather than full text — a punctuation fix elsewhere on the page shouldn't invalidate a boundary finding, but an actual boundary change always should.
• Wired into model_routing_config.json, budget_config.json (disabled by default, given priority ahead of translation per the plan's "this task type is upstream of the others" reasoning), and schedule_runner.ts.
• segmentation_audit_cli.ts for manual runs, matching rashi_tosafot_translation_cli.ts's conventions.

Test plan

• npx jest — 86 suites / 838 tests pass
• npx tsc (pre-commit check) — clean
• npx eslint on all changed files — no errors (only pre-existing no-console warnings on CLI/scheduler scripts)
• Smoke-tested segmentation_audit_cli.ts, schedule_runner.ts, and status_cli.ts via ts-node against real local state (new task type shows up correctly, disabled by default, no-ops safely)
