feat(notifications): NOTICE_KIND enum, schema v2 dedup, sf-db cleanup

- notification-store: schema v2 — repeatCount/lastTs merge for non-blocking
  notices; NOTICE_KIND enum (SYSTEM_NOTICE, TOOL_NOTICE, BLOCKING_NOTICE,
  USER_VISIBLE) for renderer classification without message parsing
- sf-db: remove gate_runs and audit_events tables (replaced by uok audit.js
  and trace-writer); schema reduced by ~370 lines
- notify-interceptor: tag auto-mode system notices with NOTICE_KIND.SYSTEM_NOTICE
- auto-prompts, guided-flow, system-context: use NOTICE_KIND on emit calls
- cli-status: expanded headless status surface + test coverage
- headless-types: new status fields
- Makefile/justfile: dev workflow improvements
- record-promoter, requirement-promoter: minor cleanup
- sf-db-migration tests: updated for dropped tables
- uok-gate-runner, uok-metrics, uok-outcome, uok-status tests: updated

    ```
    The mode determines how the run-uat agent executes checks. For slices verified only by build commands, grep checks, and automated tests you may omit this block — `complete_slice` then injects a default `artifact-driven` section ahead of your body so parsers still classify the artifact.

 10b. Scan task summaries and the slice's activity log for sf-internal anomalies that the per-task agents may not have reported individually — repeated `Git stage failed`, `Verification failed … advisory`, `Safety: N unexpected file change(s)`, brittle gate predicates, etc. For any genuine sf-the-tool defect that surfaced during this slice but was NOT already filed via `report_issue`, file it now via `report_issue` with appropriate severity. This is the slice-level sweep — task-level agents file individual reports during execution; the slice-close agent catches systemic issues only visible across multiple tasks.
 11. Call `complete_slice` with the camelCase fields `milestoneId`, `sliceId`, `sliceTitle`, `oneLiner`, `narrative`, `verification`, and `uatContent`, plus any optional enrichment fields you have. Do NOT manually mark the roadmap checkbox — the tool writes to the DB, renders `{{sliceSummaryPath}}` and `{{sliceUatPath}}`, and updates the ROADMAP.md projection automatically.
 12. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.

 17. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.
 17b. **sf-internal anomalies and observations:** If during execution you observe sf-the-tool misbehaving (empty `git add --` pathspecs, brittle gate predicates, advisory-downgrade hiding real failures, false safety floods), find a prompt ambiguous or contradictory, hit workflow friction, or have an idea that would make sf better — call `report_issue`. Use `prompt-quality-issue`, `improvement-idea`, `agent-friction`, or `design-thought` kinds for non-bug observations alongside the classic bug kinds. Severity guide: `low`/`medium` for cosmetic / noisy / nice-to-have (sf continues); `high`/`critical` only when the sf issue actually prevents the task from sealing correctly (this blocks the unit). For high/critical, include `acceptance_criteria` so a future resolver has a falsifiable bar. This is distinct from `blocker_discovered` (which is about the user's plan, not about sf). Over-reporting is preferred to under-reporting at this stage.
 17c. **Self-feedback is a TRIAGE inbox, not a work queue.** Do NOT autonomously pick up entries from `.sf/SELF-FEEDBACK.md` or `~/.sf/agent/upstream-feedback.jsonl` and try to fix them — those are open observations awaiting human/triage-agent review to decide which become scheduled work, duplicates, or wontfix. Your scope is the task plan you were dispatched with. The only interaction your task should have with self-feedback is FILING new entries (via `report_issue`) when you observe sf-internal anomalies. The exception: if a self-feedback entry id is *explicitly named* in your task plan as the work to be done, treat it as you would any other planned item — read its `acceptanceCriteria`, satisfy each, and cite the entry id + criteria met in your task summary's `narrative` so the resolution is traceable.

+Plan milestone {{milestoneId}} ("{{milestoneTitle}}"). Decisions and requirements are injected from the database into your system context — respect existing decisions and treat Active requirements as the capability contract. If no requirements are present, treat that as a planning gap: derive the minimum requirement coverage from current project evidence, persist it through `save_requirement`, and explicitly note missing coverage. Use the **Roadmap** output template below to shape the milestone planning payload you send to `plan_milestone`. Start the `vision` field with the milestone purpose before implementation detail, include the structured `productResearch` payload when the work is product-facing, workflow-facing, developer-experience, or market-positioning, and make each slice `goal` state the slice purpose before mechanics. If the milestone changes how SF is driven, observed, integrated, or automated, keep the axes separate in the roadmap: surface (TUI/CLI/web/editor/machine), protocol (ACP/RPC/stdio/HTTP/wire), output format (text/json/stream-json), run control (manual/assisted/autonomous), and permission profile (restricted/normal/trusted/unrestricted).

 Before calling `plan_milestone`, run a bounded **Vision Alignment Meeting** for the milestone and roadmap as a real multi-agent review. Use the `subagent` tool in `mode: "debate"` with `rounds: 2` and a separate task for each participant lens below. Do **not** merely simulate every participant inside this planner response. Use only supported agent names: `planner`, `reviewer`, `researcher`, and `scout`. Put the stakeholder role name inside the task text; do not invent agent names such as `combatant`, `delivery-lead`, `product-manager`, or `customer-panel`. If the `subagent` tool is unavailable or fails after one retry, record that explicitly in `trigger` and run the structured meeting inline as a degraded fallback. This is allowed to be broader and more nuanced than slice planning. Include at least these participant lenses:
