- Add GET /stream SSE endpoint to aggregator.py; state is pushed
instantly on every change instead of fetched every 2s
- Replace setInterval polling in index.html with EventSource;
onerror shows the ( ?.?) face and auto-reconnect is handled by
the browser natively
- Fix ModuleNotFoundError in detectors: inject project root into
PYTHONPATH when launching subprocesses from kao.py
- Update openapi.yaml, CLAUDE.md, README.md with /stream endpoint
- Remove completed SSE item from TODO.md

Kao is a display, not a monitor — external systems push events via REST
rather than Kao polling things itself. Update CLAUDE.md to reflect this:
- New Design Philosophy section making the REST-first approach explicit
- Architecture diagram updated to show external systems as the push source
- Detectors section demoted to "Legacy Detectors" with a note to prefer push
- TODO.md added with planned REST API improvements (SSE, notify queue,
sticky notifications, named presets, batch notify, /history endpoint)
and display improvements (brightness curve, scrolling ticker)

- index.html: fix playWarningSound (440→550 Hz, louder), fix playBubbleSound
(audible volumes/durations), add looping klaxon sound (sawtooth wah-wah),
stopKlaxon() on tap and state clear, bump VERSION to v2.2.0
- kao_tui.py: add klaxon to SOUNDS list, drop notify duration 5→2s for
faster iteration; also include improved post() error reporting
- CLAUDE.md: add kao_tui.py to file structure, fix personality table
(remove ˙▿˙ row not in aggregator), add klaxon to sound list
- README.md: add klaxon to sound list, update counts
- openapi.yaml: bump version to 2.2.0, add klaxon to sound enum

- Emote face is now stable all day; /wake picks a fresh random face each
morning instead of rotating every 5 minutes. Removes EMOTE_ROTATION_INTERVAL
and last_emote_change entirely.
- Added 10 new synthesized sounds for /notify: doorbell, knock, ding, blip,
siren, tada, ping, bubble, fanfare, and alarm (loops until tapped or TTL
expires). stopAlarm() wired into tap handler and handleStateChange().
- openapi.yaml: new sound names added to enum.
- CLAUDE.md / README.md updated to reflect both changes.

- Extract shared send_event/clear_event into detectors/base.py, removing
~150 lines of duplication across all 6 detectors
- Fix default aggregator URL from port 5000 to 5100 in all detectors
- Standardize cpu.py and memory.py to use active_alerts set pattern
- Fix immediate emote rotation on startup (last_emote_change = time.time())
- Extract magic numbers to named constants in aggregator
- Protect write_status() with try/except OSError
- Fix notify event ID collision with monotonic counter
- Replace blocking stream_output() with background daemon threads in kao.py

Add /clear-all endpoint and wire it to the tap handler so tapping the
display dismisses active warnings/critical alerts. Fix docker detector
to track restart count deltas instead of relying on the transient
"restarting" state. Wrap cleanup thread in try/except so it can't die
silently and leave events stuck forever.
