z23 b810711e4e fix(gateway): strip language tag from Slack fenced code blocks
Slack's mrkdwn does not strip the optional language tag from fenced
code blocks like GitHub-flavored markdown does — it renders
```text\nfoo\n``` as a code block whose literal first line is "text".
The agent emitted ```text fences around raw command output, which
surfaced "text" as the first line of every such block.

Drop the tag from the opening fence in format_message() before stashing
the block behind a placeholder. Stripping only fires for a genuine
opening fence — a ``` at the start of a line, tagged with a single
token (no spaces or backticks) — and the original line ending is
preserved. The fence-protection regex deliberately matches loosely, so
a mid-line ``` (e.g. an inline ```span``` wrapping across a newline)
can be grouped as an "opening fence" whose first line is real content;
differential fuzzing against the pre-change formatter (40k generated
messages) confirms the only behavioral delta is the tag strip itself.

The Block Kit renderer is unaffected: render_blocks() intercepts fences
itself before mrkdwn_fn is applied, so this only changes the mrkdwn
surfaces that still go through format_message() — the plain-text
fallback field (notifications, search indexing, accessibility),
slash-command ephemeral replies, and standalone cron delivery.

Originally written against gateway/platforms/slack.py; ported to
plugins/platforms/slack/adapter.py after the adapter migration in
5600105478.

Manually verified against a live Slack workspace (pre-migration
adapter; the ```text case strips identically) — code blocks no longer
carry a literal "text" first line.
