Reorganize all 5 skills from loose `.md` files (and one
partially-formatted `commit_msg/`) into the documented
`subdirectory/SKILL.md` format with YAML frontmatter.
Deats,
- `commit_msg/` -> `commit-msg/` w/ enhanced frontmatter:
`argument-hint`, `disable-model-invocation`,
`allowed-tools`, dynamic `!` context injection for
staged diff + recent log, `$ARGUMENTS` support
- `piker_profiling.md` -> `piker-profiling/SKILL.md` +
`patterns.md` for detailed profiling patterns
- `piker_slang_and_communication_style.md` ->
`piker-slang/SKILL.md` + `dictionary.md` +
`examples.md`
- `pyqtgraph_rendering_optimization.md` ->
`pyqtgraph-optimization/SKILL.md` + `examples.md`
- `timeseries_numpy_polars_optimization.md` ->
`timeseries-optimization/SKILL.md` +
`numpy-patterns.md` + `polars-patterns.md`
Also,
- all background skills use `user-invocable: false`
for auto-application when relevant.
- use a hyphen convention across all dir names.
- content is now split into supporting files linked from each
`SKILL.md`.
