Add python3 / python rewrite support

[sebagavilan]

Problem

rtk discover shows ~691 python3 heredoc commands and ~289 python3 script invocations not being rewritten. rtk rewrite has no rule for python3 or python.

Patterns to support

Pattern	Example	Count (30d)
python3 << 'PYEOF'	Inline heredoc scripts	~691
python3 script.py	Script execution	~289
python -m <module>	Module execution (unittest, py_compile)	~83

Reproduction

$ rtk rewrite "python3 << 'PYEOF'"
# exit 1, no output — no rewrite rule

$ rtk rewrite "python3 scripts/my_script.py"
# exit 1, no output

$ rtk rewrite "python -m unittest discover -s ."
# exit 1, no output

Environment

• rtk 0.30.1
• macOS (Darwin 23.5.0)

Impact

Python heredoc scripts often produce large DataFrames/dicts as output — high token savings potential. Combined ~1,063 commands over 30 days.

Don't know if this is helpful... But I'm working in a project that focuses on mac OS only and python3 is the default. Was running .34 and ran discover. Agent is walking across my skills folder a bunch as I develop the skills out. Also seems to be hitting json.tool quite a bit instead of using jq.

-> % rtk --version
rtk 0.34.3

-> % rtk discover
[...]
TOP UNHANDLED COMMANDS -- open an issue?
----------------------------------------------------
Command                  Count    Example
python3                    450    python3 /worktrees/roadmap/.claude/ski..
[...]

Predominant pattern within my project seems to be using json.tool

cat /folder/super-large-file.json | python3 -m json.tool | grep -A 30
