* fix(#381): make gsd_run launcher reachable in fresh-shell-per-block runtimes
On runtimes that execute each fenced bash block in a separate shell process
(e.g. Claude Code — documented behavior: each Bash command is a separate
process; inline shell functions and exported vars do not persist between
calls), the once-per-file gsd_run() function was undefined in every block
after the preamble block, and the call was swallowed by
`2>/dev/null || echo "{}"` into silent empty state.
Fix (budget-neutral session-level resolution):
- Ship gsd-core/bin/gsd_run, a POSIX sh wrapper that symlink-resolves its own
location and execs the co-located gsd-tools.cjs. Exposed on PATH via the npm
`bin` field (global installs) and shipped to local installs via the recursive
gsd-core/ copy.
- The per-file launcher preamble now appends `export PATH='<bindir>':"$PATH"`
to the file named by $CLAUDE_ENV_FILE (Claude Code's documented
env-persistence mechanism) so later fresh-shell blocks resolve gsd_run from
PATH. Guarded as a strict no-op when CLAUDE_ENV_FILE is unset; the inline
gsd_run() definition remains the fallback for all other runtimes. The
single-quoted dir neutralizes shell metacharacters at source time.
- Propagated via scripts/sync-runtime-launcher.cjs to all launcher-using files.
- XL workflow byte budget 93000 -> 93200 (the ~130B clause pushes plan-phase.md
to 93135; legitimate content growth, ratchet-up per #717).
Regression tests (I)/(J) in runtime-launcher-parity.test.cjs cover wrapper
delegation and end-to-end PATH persistence (sourcing the env file with a
space-bearing install path).
Known limitation: an install path containing a literal single-quote yields a
malformed env-file line and falls back to the status quo (no regression);
rare on sanitized home directories.
Closes#381

* test(#381): scope test (J) bare-PATH execution to POSIX (Windows Git Bash exec bit)
Windows Git Bash (msys2) does not honor Node's chmod exec bit for
PATH-executing extension-less scripts, so the bare `gsd_run` command lookup
failed there even though the env-file PATH persistence was correct. The
env-file content assertions (the fix's actual cross-platform logic) still run
on every platform; only the final source-and-execute sub-step is gated to
non-win32. Global installs on Windows are covered by npm's generated bin shim.
