feat(teams): add native Teams bridge and message actions

[patroza]

Summary

• port the remaining Teams work from the legacy private repository:
  • aaaomega/t3code-pvt#1 — Graph polling intake, attachments, history, and manual triggers
  • aaaomega/t3code-pvt#6 — Teams message-action design
  • aaaomega/t3code-pvt#30 — multi-platform adapter plan
• add a transport-neutral T3 start/continue path shared by Discord and Teams
• add a Discord-free Teams SDK entrypoint with authenticated native message handling
• deliver final T3 answers back to Teams and support stop, approve <request-id>, and deny <request-id>
• implement the Start T3 investigation message action for triggering T3 from a selected message without installing the conversational bot in that conversation
• support native, t3-only, and legacy discord Graph-poller delivery modes
• add the Teams app manifest template, environment configuration, tests, and step-by-step deployment guide

Operating modes

Mode	Discord required	Bot participant required	Result delivery
Native Teams replacement	No	Yes	Final answer in Teams
Teams message action	No	No	Private confirmation; follow in T3 Code
Graph polling / t3-only	No	No	T3 Code + optional workflow webhook acknowledgement
Graph polling / discord	Yes	No	Discord compatibility bridge

Provenance

Source	Ported behavior
pvt#30	Chat-platform adapter plan
pvt#1	Teams Graph intake, history, images, trigger modes, channel mapping
pvt#6	Message-action requirements, now implemented

Adapted locally

• rebased onto the current fork/discord overlay and current link-store schema
• replaced Discord-only orchestration with startOrContinueT3Turn
• updated the Teams integration to the current @microsoft/teams.apps SDK
• made DISCORD_BOT_TOKEN optional for the Teams-only entrypoint
• retained all Teams features behind explicit TEAMS_* flags

Validation

• vp test run apps/discord-bot/src/features/TeamsNativeApp.test.ts apps/discord-bot/src/config.test.ts apps/discord-bot/src/teams/config.test.ts apps/discord-bot/src/teams/presentation.test.ts apps/discord-bot/src/store/ThreadLinkStore.test.ts ✅ (33 tests)
• vp run --filter @t3tools/discord-bot typecheck ✅
• vp check ✅ (existing warnings only)
• ELECTRON_SKIP_BINARY_DOWNLOAD=1 vp run -r --cache --log labeled typecheck ✅

Deployment

See docs/integrations/microsoft-teams-discord-bot.md for tenant registration, app packaging, channel mapping, Teams-only startup, message-action rollout, Graph permissions, and production checks.

   • fix: preserve fork adaptations across Tim update #6 Plan Teams message action support → docs/integrations/microsoft-teams-message-action-plan.md
   • Import mobile pagination and bounded replay from upstream #3510 #30 already represented as the multi-platform adapter plan doc
