run_command_with_timeout piped stdout/stderr but only read them after
the child exited. When test output exceeded the 64KB OS pipe buffer,
the child blocked on write() while the parent blocked on waitpid() —
a permanent deadlock that caused every merge pipeline to hang.
Drain both pipes in background threads so the buffers never fill.

Test commands in run_project_tests now use wait-timeout to enforce a
600-second ceiling, preventing hung processes (e.g. Playwright with no
server) from blocking the merge pipeline indefinitely. Also disables
e2e tests in script/test until the merge workspace can run them safely.

Split the monolithic agents.rs into 6 focused modules:
- mod.rs: shared types (AgentEvent, AgentStatus, etc.) and re-exports
- pool.rs: AgentPool struct, all methods, and helper free functions
- pty.rs: PTY streaming (run_agent_pty_blocking, emit_event)
- lifecycle.rs: story movement functions (move_story_to_qa, etc.)
- gates.rs: acceptance gates (clippy, tests, coverage)
- merge.rs: squash-merge, conflict resolution, quality gates
All 121 original tests are preserved and distributed across modules.
Also adds clear_front_matter_field to story_metadata.rs to strip
stale merge_failure from front matter when stories move to done.
