feat(tts): resolve channel account config generically

 - Codex/agent: translate `--thinking minimal` to `low` for modern Codex models (gpt-5.5, gpt-5.4, gpt-5.4-mini, gpt-5.2) at request build time so the first turn is accepted instead of paying a wasted call + retry-with-low fallback. Older Codex models still receive `minimal` directly. Fixes #71946. Thanks @hclsys.
 - TTS/WhatsApp: add `/tts latest` read-aloud support with duplicate suppression and `/tts chat on|off|default` session-scoped auto-TTS overrides, completing the on-demand voice-note UX for current-chat replies. Fixes #66032.
+- TTS/channels: resolve channel and account TTS overrides generically, enabling Feishu and QQBot accounts to deep-merge `channels.<channel>.accounts.<id>.tts` over global and per-agent TTS config. Thanks @sahilsatralkar.
 - Plugins/tokenjuice: bump the bundled tokenjuice runtime to 0.6.3. Thanks @vincentkoc.
 - TTS/agents: allow `agents.list[].tts` to override global `messages.tts` for per-agent voices while keeping shared provider credentials and preferences in the existing TTS config surface.
 - TTS/agents: make `/tts audio`, `/tts status`, and the `tts` agent tool honor the active `agents.list[].tts` voice/provider override.

+global TTS config, so multi-bot Feishu setups can keep shared provider
