* fix(tests): allowlist execute-phase.md in prompt-injection scan
execute-phase.md grew to ~51K chars after the code-review gate step
was added in #1630, tripping the 50K size heuristic in the injection
scanner. The limit is calibrated for user-supplied input — trusted
workflow source files that legitimately exceed it are allowlisted
individually, following the same pattern as discuss-phase.md.

* feat(security): improve prompt injection scanner with 4 detection layers (#1838)
- Layer 1: Unicode tag block U+E0000–U+E007F detection in strict mode (2025 supply-chain attack vector)
- Layer 2: Character-spacing obfuscation, delimiter injection (<system>/<assistant>/<user>/<human>), and long hex sequence patterns
- Layer 3: validatePromptStructure() — validates XML tag structure of agent/workflow files against known-valid tag set
- Layer 4: scanEntropyAnomalies() — Shannon entropy analysis flagging high-entropy paragraphs (>5.5 bits/char)
All layers implemented TDD (RED→GREEN): 31 new tests written first, verified failing, then implemented.
Full suite: 2559 tests, 0 failures. security.cjs: 99.6% stmt coverage.

* feat(planner): add reachability_check step to prevent unreachable code
Closes#1495
* fix: trim gsd-planner.md below 50000-char limit after rebase
The reachability_check addition pushed the file to 50,275 chars when
merged with the assign_waves additions from #1600. Condense both sections
while preserving all logic; file is now 49,859 chars.

* fix(security): normalize CRLF before prompt-stuffing length check
On Windows, git checks out files with CRLF line endings. JavaScript's
String.length counts \r characters, so a 49,859-byte file measures as
51,126 chars on Windows — falsely tripping the 50,000-char security
scanner. Normalize CRLF → LF before measuring in security.cjs and in
the reachability-check test.

* fix: trim gsd-planner.md to stay under 50000-char limit after merge with main
After rebasing onto main (which added mcp_tool_usage block), combined content
reached 50031 chars. Remove suggested log format from assign_waves rule to
bring file to 49972 chars, well under the 50000-char security scanner limit.

The original PR (#1337) used \Z in a JavaScript regex, which is a
Perl/Python/Ruby anchor — JavaScript interprets it as a literal match
for the character 'Z', silently truncating expected text containing
that letter. Replace with a two-pass approach: try next-key lookahead
first, fall back to greedy match to end-of-string.
Also remove the redundant `to=all:` pattern in sanitizeForDisplay()
since it is a subset of the existing `to=[^:\s]+:` pattern.
Add regression tests proving the Z-truncation bug and verifying
expected blocks at end-of-section parse correctly.
