Fix files regex so opcode-metadata hooks trigger on tools/opcode_metadata/* changes

The current regex tools/opcode_metadata/* doesn’t match real files like tools/opcode_metadata/opcodes.py, so both manual hooks only match crates/compiler-core/src/bytecode/instruction.rs. Update both hook files patterns to tools/opcode_metadata/.*.

💡 Proposed fix 
-        files: '^(crates/compiler-core/src/bytecode/instruction\.rs|tools/opcode_metadata/*)$'
+        files: '^(crates/compiler-core/src/bytecode/instruction\.rs|tools/opcode_metadata/.*)$'
...
-        files: '^(crates/compiler-core/src/bytecode/instruction\.rs|tools/opcode_metadata/*)$'
+        files: '^(crates/compiler-core/src/bytecode/instruction\.rs|tools/opcode_metadata/.*)$'

In @.pre-commit-config.yaml around lines 46 - 47, The hook `files` regex
currently uses `tools/opcode_metadata/*` which doesn't match files like
`tools/opcode_metadata/opcodes.py`; update both occurrences of the `files`
pattern in the pre-commit config (the lines with `files:` that currently contain
`tools/opcode_metadata/*`) to use `tools/opcode_metadata/.*` so the
opcode-metadata hooks trigger on changes under that directory (keep
`pass_filenames: false` as-is).
