feat: add Slack reaction feedback to LangSmith (#1231)
* feat: add Slack reaction feedback to LangSmith

Record Slack reaction feedback against explicitly mapped LangGraph runs so user ratings are idempotent and tied to the message they reacted to.

* Address review feedback on Slack reaction → LangSmith feedback

- langsmith.py: drop lru_cache on _build_langsmith_feedback_clients so
  rotated keys / late env hydration are picked up; dedupe by (key, url)
  tuple instead of key alone so the same key pointing at different
  endpoints (cloud + self-hosted) builds both clients.
- langsmith.py: treat LangSmithNotFoundError on delete_feedback as
  success — out-of-order or redelivered reaction_removed events would
  otherwise loop forever on Slack's retry policy.
- slack_feedback.py: include channel_id in _feedback_key so the same
  message_ts in two channels can't collide on the same feedback id.
- slack_feedback.py: treat conflicting +/- reactions from one user as
  ambiguous (clear feedback) instead of averaging to a misleading 0.5.
- slack_feedback.py + slack.py + webapp.py: gate reaction handling to
  the user who triggered the run (stored in the slack_run_map mapping
  alongside run_id). Prevents bystanders in shared channels from
  polluting eval feedback.

"""Post a message to the current Slack thread.
Use this for clarifying questions, mid-run progress updates, and the final
summary. You can call this multiple times during a run — if you're about to
do long-running work (cloning, large refactors, big test runs) consider
posting a brief status update first so the user knows what's happening.
Always end the run with a final reply summarizing what you did.
Format messages using Slack's mrkdwn format, NOT standard Markdown.
Key differences: *bold*, _italic_, ~strikethrough~, <url|link text>,
bullet lists with "• ", ```code blocks```, > blockquotes.
Do NOT use **bold**, [link](url), or other standard Markdown syntax.
To mention/tag a user, use Slack's mention format: <@USER_ID>.
You can find user IDs in the conversation context (e.g. @Name(U06KD8BFY95)).
Example: <@U06KD8BFY95> will tag that user in the message."""
