ace-pm 80ce0f4855 feat(source): enable running gsd directly from source checkout
Adds bin/gsd-from-source shell wrapper that bun-runs src/loader.ts, so
local commits are live without reinstalling gsd-pi. Patches loader.ts
to respect a pre-set GSD_BIN_PATH (previously it clobbered the env var
with process.argv[1], forcing subagent spawns to point at the .ts
loader path which child_process.spawn can't execute).

Why: working on fixes like #4251 required full `bun install -g --trust
gsd-pi` cycles plus longcat shim re-patching for every iteration.

# gsd-from-source — run GSD directly from this source checkout via bun.
#
# Purpose: every local commit in this repo (e.g. the #4251 fix) is live
# immediately without reinstalling the bun-packaged gsd-pi. Subagents can
# spawn gsd by pointing GSD_BIN_PATH at this script instead of dist/loader.js.
#
# Contract:
# - Executable shim spawn() / exec() can launch directly.
# - Exports GSD_BIN_PATH before handing off to loader.ts so loader.ts's
# `GSD_BIN_PATH ||= process.argv[1]` branch preserves the shim path
# instead of clobbering it with the .ts loader path (which is not
# directly executable by child_process.spawn).
#
# Requirements: bun on PATH, node_modules populated (`bun install` once).
