Reworked the system-self-improve skill end-to-end:
1. self-improve-edit:
- Inline text replacement (no longer depends on org-modify which was
in an unexported skill package and broken)
- After editing a .org file, automatically tangles to .lisp, compiles,
and loads the result into the running daemon
- Memory snapshot before edit for rollback safety
2. self-improve-balance-parens:
- New utility: detects unbalanced parens via the Lisp reader, counts
open/close parens using loop+char= (avoiding #\( #\) which
confuse text-based paren counting)
- Returns balanced code or nil if already balanced
3. self-improve-repair-syntax:
- New driver: locates a skill's .org source file, extracts all lisp
blocks, runs each through balance-parens, writes fixes back,
then tangles+compiles+loads
4. self-improve-fix:
- Diagnosis phase (unchanged): pattern-matches error logs for Reader
Error, Undefined symbol, or PACKAGE errors
- Repair phase (new): dispatches syntax errors to
self-improve-repair-syntax; other error types return diagnosis
with :repaired nil
5. Infrastructure:
- org-tangle-file: reads #+PROPERTY: header-args:lisp :tangle from
any .org file, extracts blocks, writes .lisp, compiles, loads
- org-extract-lisp-blocks: extracts all #+begin_src lisp blocks
from an Org content string
