can1357 0a71899499 feat(ast,natives,coding-agent)!: multi-pattern ast_find and ops-based ast_replace
BREAKING CHANGE: ast_find parameter 'pattern' (string) is replaced by
'patterns' (string[]). ast_replace parameters 'pattern' + 'rewrite' are
replaced by 'ops: Array<{ pat: string; out: string }>'.

Native (pi-natives / crates/pi-natives):
- astFind accepts patterns[] array; all patterns run per file, results
  merged and sorted by path/line/column before offset+limit are applied
- astReplace accepts rewrites Record<string,string>; all patterns compiled
  once upfront and applied per file in a single pass
- Deterministic result ordering via BTreeSet/BTreeMap

Coding-agent tools:
- ast_find: multi-pattern deduplication, '>>' prefix on match-start lines,
  padded line numbers, directory-tree grouping (# dir / ## └─ file headers),
  scopePath/files/fileMatches in tool details
- ast_replace: ops[] interface with duplicate-pattern rejection, diff-style
  (-before/+after) previews grouped by directory, parse errors shown on
  zero-replacement path, fileReplacements in tool details
- Tool prompts updated to document new interfaces with multi-pattern examples
- Task item id maxLength raised from 32 to 48 characters
- Added ast_replace tool test suite
