giles 76ce0c3ecb Add 15 new MCP tools to sx-tree: project-wide search, smart editing, dev workflow ...

New comprehension tools:
- sx_find_across: search pattern across all .sx files in a directory
- sx_comp_list: list all definitions (defcomp/defisland/defmacro/defpage/define)
- sx_comp_usage: find all uses of a component across files
- sx_diff: structural diff between two .sx files (ADDED/REMOVED/CHANGED)
- sx_eval: REPL — evaluate SX expressions in the MCP server env

Smart read_tree enhancements:
- Auto-summarise large files (>200 lines)
- focus param: expand only matching subtrees, collapse rest
- max_depth/max_lines/offset for depth limiting and pagination

Smart editing tools:
- sx_rename_symbol: rename all occurrences of a symbol in a file
- sx_replace_by_pattern: find+replace first/all pattern matches
- sx_insert_near: insert before/after a pattern match (top-level)
- sx_rename_across: rename symbol across all .sx files (with dry_run)
- sx_write_file: create .sx files with parse validation

Development tools:
- sx_pretty_print: reformat .sx files with indentation (also used by all edit tools)
- sx_build: build JS bundle or OCaml binary
- sx_test: run test suites with structured pass/fail results
- sx_format_check: lint for empty bindings, missing bodies, duplicate params
- sx_macroexpand: evaluate expressions with a file's macro definitions loaded

Also: updated hook to block Write on .sx files, added custom explore agent.
