SEA-4.3-COMPLETE

SEA-4.3-COMPLETE

## Summary
Implemented the `/skill reset` command in `skill_controller.py`. The reset command wipes a skill's `activation-log.jsonl` and restores `state.json` to factory defaults (zeroed counters, re-seeded hot/cold topics from SKILL.md, cleared mute status). Includes interactive confirmation prompt (skippable with `--confirm`), JSON output mode, and pre-reset stats in the response.

## Changes
- File: `[home-path]` — modified
- Added `SEED_TOPICS` constant (13 skills × hot/cold topic lists from SEA-1.1)
- Added `DEFAULT_CONTEXT_WINDOW` and `DEFAULT_CONFIDENCE_CALIBRATION` constants
- Added `build_default_state()` helper to construct factory-default state.json
- Added `reset_skill()` function: captures pre-reset snapshot, writes fresh state, truncates log
- Added `reset` CLI subcommand with `--confirm`/`-y` and `--json` flags
- Cleaned up unused imports (`os`, `time`)
- Updated docstring to reflect SEA-4.2 + SEA-4.3
- File: `CREATIVE_EVOLUTION_SEA_v1.md` — updated task 4.3 status to Complete

## RTD Verification
- [x] Structure: all files present, no new files created outside completion report
- [x] Compilation: `py_compile` passes, `--help` renders correctly
- [x] Integration: extends existing `skill_controller.py` patterns (load_state/save_state/log_event), no broken refs
- [x] Content: reset wipes log, restores state.json to exact SEA-1.1 defaults, clears mute fields
- [x] User Journey: tested reset on `phi:veritas` (clean), `art:snark` (clean), `nav:organic` (mute→reset clears mute)
- [x] Deployment: committed

Test Results

Test 1: Reset skill with 0 activations (phi:veritas)

$ python skill_controller.py reset phi:veritas --confirm --json
{
  "action": "reset",
  "skill": "phi:veritas",
  "pre_reset": {"total_activations": 0, "useful_activations": 0, "suppressed_count": 1, "was_muted": false},
  "log_entries_wiped": 2
}

- state.json: suppressed_count 1→0, hot/cold topics preserved, no muted fields

Test 2: Human-readable output (art:snark)

$ python skill_controller.py reset art:snark --confirm
  🔄 art:snark reset to factory defaults
     Activations cleared: 0 total, 0 useful
     Log entries wiped: 2

Test 3: Mute then reset clears mute (nav:organic)

$ python skill_controller.py mute nav:organic --reason "testing"
  🔇 nav:organic muted — testing
$ python skill_controller.py reset nav:organic --confirm
  🔄 nav:organic reset to factory defaults
     Activations cleared: 0 total, 0 useful
     Log entries wiped: 1
     Mute status: cleared (was muted)

Test 4: Invalid skill name

$ python skill_controller.py reset invalid:skill --confirm
ERROR: Unknown skill 'invalid:skill'. Valid: phi:veritas, ...
