* feat: add stop/backtrack capture classifications for milestone regression (#3487)
Adds 4-layer methodology for halting auto-mode and backtracking to
previous milestones when captures indicate the user wants to stop or
that a milestone missed critical features:
1. Type layer: "stop" and "backtrack" classification types in captures.ts
2. Guard layer: pre-dispatch stop check in runGuards() pauses auto-mode
before the next unit dispatches
3. Resolution layer: executeBacktrack() writes BACKTRACK-TRIGGER.md and
milestone regression markers for state machine detection
4. Protection layer: revertExecutorResolvedCaptures() detects and reverts
captures silenced by non-triage agents (resolved without classification)
Also adds fast-path stop detection in auto-post-unit.ts that pattern-matches
pending capture text for stop keywords without waiting for triage.
Closes#3487

* feat: add slice-level skip with gsd_skip_slice tool (#3477)
Adds "skipped" as a closed status alongside "complete" and "done":
- status-guards.ts: isClosedStatus() recognizes "skipped"
- state.ts: isStatusDone() recognizes "skipped"
- gsd-db.ts: getActiveSliceFromDb() skips slices with status "skipped"
- db-tools.ts: new gsd_skip_slice tool for rethink and manual use
- rethink.md: added "Skip a slice" operation to rethink prompt
- rethink.ts: buildRethinkData shows skipped slice counts
Skipped slices satisfy dependencies for downstream slices, allowing
auto-mode to advance past them. Slice data is preserved for reference.

* fix: resolve 4 issues found in adversarial review of PR #3488
1. triage-ui.ts: Restore stop/backtrack entries in CLASSIFICATION_LABELS
and ALL_CLASSIFICATIONS — the Record<Classification, ...> type requires
all union members, and runtime lookups would crash on stop/backtrack.
Also auto-confirm stop/backtrack in the triage confirmation flow
(matching the triage-captures.md prompt directive).
2. triage-resolution.ts: Replace require("node:fs") in clearBacktrackTrigger
with ESM import of unlinkSync — consistent with the rest of the codebase.
3. auto-post-unit.ts: Anchor STOP_PATTERN regex to start-of-string (^) to
prevent false positives on captures like "add a pause button" or "stop
the timer from re-rendering" which are feature descriptions, not halt
directives.
4. status-guards.test.ts: Add missing test case for isClosedStatus("skipped")
to cover the new status value.

* fix: update tool-naming test count for gsd_skip_slice
The new gsd_skip_slice tool (no alias) brings the total from 29 to 30.
