Code Review
This pull request modernizes the codebase by updating datetime references to use UTC, adopting the | operator for type unions, and refactoring conditional logic into ternary expressions. It also includes significant formatting updates, import cleanups, and an optimization of Postgres transaction handling. I have no feedback to provide.

Hardens the socket-mode port against the seven review findings on PR #86: * Add ``connect_timeout_s`` config (default 30s) and wrap the initial socket-mode handshake in ``asyncio.wait_for`` so a hung ``SocketModeClient.connect()`` can't make ``initialize()`` block forever (hazard #11). On timeout we tear the loop down before raising. * Reject forwarded socket events whose ``timestamp`` field is outside the same 5-minute window ``_verify_signature`` enforces, so a captured forwarded payload can't be replayed indefinitely (hazard #12). * Narrow the ``contextlib.suppress`` in ``stop_socket_mode`` to ``CancelledError`` only — surprising loop crashes are no longer silently swallowed during shutdown. * Replace ``asyncio.get_event_loop().create_task`` in the socket-mode ``wrap_async`` helper with ``get_running_loop`` (Python 3.12+ compatibility, hazard #5). * Have the socket-mode interactive branch ack with ``response_action: errors`` instead of an empty ack when dispatch raises — an empty ack on ``view_submission`` silently closes the modal so the user sees no signal anything went wrong. * Drop ``is_ext_shared_channel`` from the synthesized ``event_callback`` payload in the socket-mode events_api branch so socket and webhook paths feed identical shapes into ``_process_event_payload`` (hazard #7). * Add a regression test firing two concurrent ``_route_socket_event`` events_api dispatches for different teams via ``asyncio.gather`` to pin down the existing ``copy_context()`` isolation against future drift (hazard #6). Also fixes a pre-existing B010 lint warning in the test stub. https://claude.ai/code/session_01FyMxQn2BEAzmwKS1GZczKj

Independent review surfaced three actionable items: 1. **Math/escape ordering** (review #1) -- `_strip_math_regions` ran BEFORE `_strip_escape_sequences`, so input like `\$opener *unclosed text closer\$` had its two escaped `$`s paired as math, eating the `*` opener inside. Reordered: escape strip first, then math strip. Verified the original bug repro now correctly produces a closing `*`. 2. **Empty task items** (review #5) -- `r"^\[([ xX])\]\s+(.*)"` required at least one whitespace AFTER `]`, so `- [ ]` with no trailing content silently fell through to plain text. Loosened to `r"^\[([ xX])\](?:\s+(.*))?$"` -- trailing whitespace+content is now optional. `- [ ]` and `- [x]` (no trailing) both produce `listItem(checked=False/True, children=[])`. 3. **Strikethrough test strengthened** (review #7) -- the existing `test_escaped_tilde_does_not_form_strikethrough` only asserted the absence of a `delete` node. A buggy impl that dropped the tildes entirely would have passed. Added a content-shape assertion that `~~not strike~~` appears in the text leaves. Reviewer's #3 (the `r"a *b\* * c"` case) was investigated and determined NOT to be a bug -- the trailing `*` between two spaces is not a valid CommonMark closer (whitespace-flanked), so italic correctly stays open. Pre-fix behavior happened to balance by ignoring flanking; post-fix is CommonMark-correct. Pre-existing edge cases #4 (`\\*text*`) and #6 (link-text unescape implicit) are documented in the existing code; not blockers. Tests added: - `test_empty_unchecked_task_item_no_content` and `_checked_` variant - `test_remend_escaped_dollar_does_not_pair_with_unescaped_dollar` (the exact #1 repro) - `test_remend_escaped_dollar_does_not_create_phantom_math_region` - Strengthened `test_escaped_tilde_does_not_form_strikethrough` 3,625 pass / 1 pre-existing failure unrelated.
