refactor(packages/coding-agent): reorganized atom LID parsing rules

- Centralized `line-hash.ts` hash regex sources and resolved `atom.lark` via `resolveLarkLidPlaceholders`.
- Expanded `computeLineHash` to emit `>[a-z]` and `[a-z]<` hashes for brace-context anchors.
- Replaced atom/hashline parsers' hard-coded lid regex with shared `HASHLINE_HASH_RE_SRC` and lax counterparts.
- Removed `\\TEXT` continuation handling in atom rewrites and switched multi-line replacements to `+TEXT`.
- Added brace-body insertion warning when `@Lid` on `{`-ending lines inserts at non-body-safe indent.
- Suppressed duplicate auto-rebase warnings and kept unmatched `-`/`+` ranges separate in compact previews.
