refactor: adopt modular webhook architecture (#1621) + port fork customizations (#85)
* Adopt upstream modular webhook skeleton (#1621)

Apply the durable-interrupt-dispatch refactor: split the monolithic
webapp.py into a thin routing layer plus per-source handlers in
webhooks/{github,slack,linear}.py, and add completion.py, dispatch.py,
and reconcile.py. Reconcile fork divergence by keeping the Bedrock/
Fireworks cross-provider fallback, the no-agent-attribution prompt
policy, the dashboard-handoff re-export, and the Slack channel-info
cache. ci_autofix is restored on the new dispatch model in a later
commit.

Refs: #80

* Port fork webhook security delta onto modular handlers

Re-apply the fork's security customizations that #1621 did not carry:
Linear webhook replay protection (freshness window on the signed
webhookTimestamp), per-repo token-cache binding threaded through the
thread token resolvers, the INTERNAL_BOT_LOGINS self-check in the
review-finding-reply path, and a user-mapping cache refresh before
email resolution on the issue and PR-comment paths (multi-replica
staleness). Existing fork security tests pass unchanged.

Refs: #80

* Restore CI auto-fix on the modular dispatch model

Bring back ci_autofix.py and the ci_monitor graph that #1621 deleted,
re-wiring the fork's security-reviewed PR-babysitting onto the new
structure: the CI-event, autofix-toggle, and review-feedback handlers
move into webhooks/github.py and the github_webhook router re-gains the
check_run/check_suite/workflow_run/status routing plus the autofix
command and actionable-review branches. Auto-fix runs now dispatch
through dispatch_agent_run (durability + completion webhook) while
keeping the deliberate batch-while-busy skip-rule via
get_thread_active_status. Restore langgraph.json's ci_monitor entry and
the fork autofix tests (dispatch mock + import paths re-pointed).

Refs: #80

* Reformat and update docs for the modular webhook split

Point CLAUDE.md and deploy/MIGRATION.md at the new webhooks/ modules
and the dispatch/completion/reconcile contract, and mark the
user-mapping cache-refresh fix as applied on the GitHub handlers.

Refs: #80

* Restore reject backstop for autofix dispatch

A burst of near-simultaneous CI events for one head SHA can slip past
the busy-check before the dedupe SHA is recorded, so dispatch the
autofix path with multitask_strategy=reject (dev's prior platform
default) to drop duplicate concurrent creates instead of letting them
interrupt each other. Also make the completion failure-reply dedup
claim-then-post and drop the unreachable interrupted branch.

"""Shared LangGraph thread helpers for the dashboard.
The webhook triggers (Slack / Linear / GitHub) dispatch through
``agent.dispatch.dispatch_agent_run`` with ``multitask_strategy="interrupt"``,
so they no longer need a busy-check or an in-process lock. The store-queue
below is retained for the dashboard's deliberate "inject a follow-up into a
run that's already in flight" path (``thread_api.send_dashboard_message``).
