Hoshina	72e897f95a	fix(channels): fix memory hazards in channel abstraction layer ... Address 7 memory/architecture issues affecting long-running gateway processes on embedded devices (<10MB RAM): - Fix dispatcher busy-wait: remove select+default pattern that caused CPU spin after context cancellation; SubscribeOutbound handles ctx internally - Add TTL janitor for typingStops/placeholders sync.Map entries to prevent unbounded accumulation when outbound paths fail - Reduce queue buffers from 100 to 16 slots (~84% memory reduction) - Optimize SplitMessage with index-based rune operations to reduce intermediate string/rune allocations - Replace uuid.New() with atomic counter + random prefix for media scope IDs (eliminates per-call crypto/rand syscall) - Lazy channel worker creation: defer goroutine+buffer allocation until channel.Start() succeeds	2026-02-24 22:30:22 +08:00
Hoshina	f645e9a377	fix: address PR review feedback across channel system ... - MediaStore: use full UUID to prevent ref collisions, preserve and expose metadata via ResolveWithMeta, include underlying OS errors - Agent loop: populate MediaPart Type/Filename/ContentType from MediaStore metadata so channels can dispatch media correctly - SplitMessage: fix byte-vs-rune index mixup in code block header parsing, remove dead candidateStr variable - Pico auth: restrict query-param token behind AllowTokenQuery config flag (default false) to prevent token leakage via logs/referer - HandleMessage: replace context.TODO with caller-propagated ctx, log PublishInbound failures instead of silently discarding - Gateway shutdown: use fresh 15s timeout context for StopAll so graceful shutdown is not short-circuited by the cancelled parent ctx	2026-02-23 06:03:23 +08:00
Hoshina	a7276e2632	refactor(channels): move SplitMessage from pkg/utils to pkg/channels ... Message splitting is exclusively a Manager responsibility. Moving it into the channels package eliminates the cross-package dependency and aligns with the refactoring plan.	2026-02-23 05:46:34 +08:00
