fix(docs): unbreak the MDX build and read trigger config from the registry

The docs build has been failing on staging since the Smartlead merge:

  ./apps/docs/content/docs/en/integrations/smartlead.mdx
  Expected a closing tag for `<original>` before the end of `paragraph`

Tool descriptions are emitted as prose, and that path escaped only braces --
every table-cell path already escaped angle brackets. MDX reads `<` as the start
of a JSX tag, so a description like 'The copy is named "<original> - copy"' fails
the build outright. escapeMdxProse handles the MDX-hostile characters and leaves
pipes, parens and brackets alone, which are legal in prose and whose escaping
would mangle markdown links.

Trigger configuration now comes from the evaluated registry instead of regex over
source. Static parsing silently dropped every field whose builder assembled its
array imperatively or took a description as a parameter -- all ten Jira triggers
lost `webhookSecret` and `jqlFilter` that way, and Monday lost its config too, so
regenerating the docs was destructive. Reading real objects also deletes 232 lines
of parsing. Note `required` may be a condition object rather than `true`; only an
unconditional `true` renders as Required, matching the previous behavior.

Tool headings now show the tool's name ("A2A Send Message") rather than its id
(`a2a_send_message`), unformatted, across 241 generated pages. Names come from
tools/generated/tool-metadata.ts, which CI keeps in sync. These headings feed each
page's table of contents. a2a.mdx is hand-written, so its headings were updated
directly.

Also consolidates five hand-inlined copies of the escape chain into the
escapeMdxCell that already existed, and drops 44 comments that restated the line
below them. Generator: 4306 -> 4069 lines.

Every refactor step was verified against a golden manifest of all 289 generated
files -- proven deterministic across runs and proven to catch a one-character
change -- so the only output differences are the intended ones.

KNOWN GAP: extractTriggerOutputs still parses source and has the same blind spot;
it already drops one Jira output section on main. Regenerating is now safe for
trigger config but still lossy for trigger outputs.
