* fix(bash): sed replacement escaping, BSD portability, dead cleanup code

Three bugs in update-agent-context.sh:

1. **sed escaping targets wrong side** (line 318-320): The escaping
   function escapes regex pattern characters (`[`, `.`, `*`, `^`, `$`,
   `+`, `{`, `}`, `|`) but these variables are used as sed
   *replacement* strings, not patterns. Only `&` (insert matched text),
   `\` (escape char), and `|` (our sed delimiter) are special in the
   replacement context. Also adds escaping for `project_name` which
   was used unescaped.

2. **BSD sed newline insertion fails on macOS** (line 364-366): Uses
   bash variable expansion to insert a literal newline into a sed
   replacement string. This works on GNU sed (Linux) but fails silently
   on BSD sed (macOS). Replaced with portable awk approach that works
   on both platforms.

3. **cleanup() removes non-existent files** (line 125-126): The
   cleanup trap attempts `rm -f /tmp/agent_update_*_$$` and
   `rm -f /tmp/manual_additions_$$` but the script never creates files
   matching these patterns — all temp files use `mktemp`. The wildcard
   with `$$` (PID) in /tmp could theoretically match unrelated files.

Fixes #154 (macOS sed failure)
Fixes #293 (sed expression errors)
Related: #338 (shellcheck findings)

* fix: restore forge case and revert copilot path change

Address PR review feedback:
- Restore forge) case in update_specific_agent since
  src/specify_cli/integrations/forge/__init__.py still exists
- Revert COPILOT_FILE path from .github/agents/ back to .github/
  to stay consistent with Python integration and tests
- Restore FORGE_FILE variable, comments, and usage strings

* refactor: extract repeated sed escaping into _esc_sed helper

Address Gemini review feedback — the inline sed escaping pattern
appeared 7 times in create_new_agent_file(). Extract to a single
helper function for maintainability and readability.

* fix: restore combined AGENTS_FILE label in update_all_existing_agents

Gemini correctly identified that splitting AGENTS_FILE updates into
individual calls is redundant — _update_if_new deduplicates by
realpath, so only the first call logs. Restore the combined label
and add back missing Pi reference.

* fix: remove pre-escaped && in JS/TS commands now that _esc_sed handles it

The old code manually pre-escaped & as \& in get_commands_for_language
because the broken escaping function didn't handle &. Now that _esc_sed
properly escapes replacement-side specials, the pre-escaping causes
double-escaping: && becomes \&\& in generated files.

Found by blind audit.

* fix: split awk && mv to let set -e catch awk failures

Under set -e, the left side of && does not trigger errexit on failure.
Split into two statements so awk failures are fatal instead of silent.

* fix: guard empty _CLEANUP_FILES array for Bash 3.2 compatibility

On Bash 3.2, the ${arr[@]+"${arr[@]}"} pattern expands to a single
empty string when the array is empty, causing rm to target .bak and
.tmp in the current directory. Use explicit length check instead,
which also avoids the word-splitting risk of unquoted expansion.
