fix(omo-codex): bypass per-rule truncation for plugin-bundled rules

Browse Source 
The 12000-char per-rule cap exists to guard against absurd user-authored
AGENTS.md files. For PLUGIN_BUNDLED rules the plugin author already
controls the body size, and silent mid-section truncation breaks the
contract that bundled discipline lands in full.

The current bundled Hephaestus baseline is 16k chars: everything from
`# AGENTS.md` onward (Output, Success Criteria, Stop Rules, Task
Tracking) was being dropped from every Codex session without warning.

Skip truncateRule when the source is plugin-bundled; the maxResultChars
budget (40000 default) via truncateBudget still caps total injection.

Locks the behavior with two regression tests in bundled-rules.test.ts:
bundled body > maxRuleChars lands intact, project body > maxRuleChars
still truncates with the standard notice.
