## Summary
- Problem: `normalizeDirectiveWhitespace` applied whitespace-collapsing regexes globally, including inside fenced code blocks (` ``` ` / `~~~`) and indent-code-blocks (4-space / tab), corrupting indentation in assistant replies that contain code snippets
- Why it matters: Any language where indentation is significant (Python, Go, YAML, etc.) or visually meaningful would render incorrectly after stripping inline directive tags
- What changed: Stash code blocks under a Unicode private-use sentinel (`\uE000`) before normalization, run the existing prose regexes on the masked text, then restore the original blocks verbatim
- What did NOT change: All prose normalization rules are retained as-is (`\r\n`, multi-space collapse, leading blank-line strip, trailing whitespace, 3+ newline fold)
## Change Type
- [x] Bug fix
## Scope
- [ ] Gateway / orchestration
## Root Cause
- Root cause: Prose whitespace regexes were applied to the full text string with no awareness of Markdown code block boundaries
- Missing detection / guardrail: No tests covered indented content inside fenced blocks
- Contributing context: Directive tag stripping (`[[reply_to_current]]`, `[[audio_as_voice]]`) is applied before delivery, making the normalization step a silent corruption point for code-heavy replies
## Regression Test Plan
- Coverage level that should have caught this:
- [x] Unit test
- Target test or file: `src/utils/directive-tags.test.ts`
- Scenario the test should lock in: `parseInlineDirectives` with fenced/indent code blocks must preserve all leading whitespace inside those blocks
- Why this is the smallest reliable guardrail: Pure function with deterministic string in/out; no mocks needed
- If no new test is added, why not: 7 new unit tests added
## User-visible / Behavior Changes
Code blocks in assistant replies containing `[[reply_to_current]]` or `[[audio_as_voice]]` directives now retain correct indentation after the directive is stripped.

Fixes issue #61358 where isGatewayMessageChannel intermittently rejects valid third-party channel plugins (openclaw-weixin, qqbot).
The pinned registry contains authoritative channel configurations for delivery, so it should be checked first before falling back to the active plugin registry.
The inner `.*\s+` in `(?:[A-Za-z_][A-Za-z0-9_]*=.*\s+)*` creates
catastrophic backtracking because both `.*` and `\s+` can match
whitespace. When the exec tool processes commands with `VAR=value`
assignments followed by whitespace-heavy text (e.g. HTML heredocs),
the regex engine hangs permanently at 100% CPU.
Replace `.*` with `\S*` in all three instances. Shell prefix variable
assignments cannot contain unquoted whitespace in the value, so `\S*`
is semantically correct and eliminates the ambiguity.
Fixes#61881
