Fixes three interlocking concurrency leaks in the evdev hotkey listener
flagged by the atomiser full-sweep. Every spawned task is now owned by a
SupervisorHandle that broadcasts cooperative shutdown and joins every
JoinHandle with a 2s per-task timeout on stop(). Per-device attachment is
now insert-before-spawn under one mutex hold, closing the TOCTOU window.
The Tauri command layer now stores the forwarder JoinHandle alongside
the listener so reconfigures join it cleanly instead of leaking one
permanent forwarder per hotkey change.

Follow-up to 184214b. The eprintln→tracing sweep surfaced 6 existing
log::* calls in the hotkey crate that were silent at runtime — the
workspace builds tracing-subscriber without the tracing-log feature, so
log:: events never reached the tracing pipeline.
Migrating direct rather than adding a LogTracer bridge: the repo is
already standardising on tracing, the bridge adds a second logger init
path with "already initialised" edge cases, and the bridge would
indiscriminately route all log records (including future third-party
chatter), not just these known sites.
Migrated (6 sites, 2 files):
- crates/hotkey/src/linux.rs (5) — read /dev/input error, device open
debug, device-attached info, device-listener-ended warn, event-channel-
closed warn
- crates/hotkey/src/stub.rs (1) — non-Linux no-op info
Also removed the now-unused log = "0.4" dependency from
crates/hotkey/Cargo.toml. magnotia_hotkey=info filter target was
already added to init_tracing in 184214b, so these events emit at the
default level immediately.
Verification:
- cargo fmt --all -- --check
- cargo check -p magnotia-hotkey — clean
- cargo check -p magnotia — clean
- rg 'log::|eprintln!' crates/hotkey/src/ src-tauri/src/commands/ crates/ai-formatting/src/ — zero hits

Major quality pass on top of Phase 2. Five substantive changes plus
cross-cutting touches across audio, hotkey, transcription, and Tauri
command layers.
Transcription quality
- Long-audio chunking in commands/transcription.rs: Parakeet and large
file transcription now chunk-and-recompose with overlap trimming, so
the live-path chunking advantage extends to file-based workflows.
- Stateful live speech gate in commands/live.rs on top of the earlier
duplicate-boundary filtering — distinguishes start-of-speech from
mid-speech and holds state across chunks.
Auto-learning corrections
- New crates/ai-formatting/src/correction_learning.rs: extracts user
text corrections from viewer edits and proposes additions to the
active profile's vocabulary.
- src-tauri/src/commands/profiles.rs bridge for frontend-driven
confirmation of learned terms.
- src/routes/viewer/+page.svelte hooks the learning path into the
segment-edit flow so corrections feed profile_terms without a
separate 'train this profile' UX.
Transcript profile provenance
- Migration v8 (crates/storage/src/migrations.rs) adds profile_id to
transcripts, defaulting to DEFAULT_PROFILE_ID so existing rows stay
valid.
- crates/storage/src/database.rs: TranscriptRow + CRUD carry profile_id.
- src-tauri/src/commands/transcripts.rs: add_transcript accepts and
persists profile_id.
- DictationPage.svelte + FilesPage.svelte send activeProfileId on
capture so learned corrections are attributed to the right profile.
Cleanup prompt contract
- crates/ai-formatting/src/llm_client.rs hardened: the CLEANUP_PROMPT
now specifies concrete do/do-not rules, ready for a real model-backed
cleanup pass. The llm_client is still a stub — kon-llm remains unwired
— but the prompt shape is final.
Cross-cutting polish
- Minor touches in audio (capture/decode/resample), hotkey (lib/linux/stub),
core, transcription (concurrency/model_manager/local_engine/whisper_rs),
and the rest of src-tauri/src/commands/*: error-path tightening, log
clarity, TS-migration follow-ups (@ts-nocheck additions for incremental
typing).
Verified locally: npm run check, cargo test -p kon-ai-formatting,
cargo test -p kon-storage, cargo test -p kon --lib commands::live::tests,
cargo check — all green.
Scope boundary: kon-llm crate is still a stub; task extraction remains
rule-based. Bundled local-LLM runtime is the next clean step and is not
in this commit.

Add kon-hotkey crate with evdev-based global hotkey capture that works on
Wayland (and X11). Patterns from whisper-overlay: per-device async listeners,
inotify hotplug with udev permission retry, watch channel for live config
updates. Frontend detects Wayland at startup and selects evdev or
tauri-plugin-global-shortcut automatically.
Model downloads now support HTTP Range resume for interrupted downloads and
optional SHA256 integrity verification (incremental, no second pass).
