Krzysztof kuhy Rudnicki b5c357a011 Refresh the handoff: python_pkg done, 142 left, shell rules recorded
Updates the counts (183 -> 142, python_pkg 50 -> 0) and records what the
eight python_pkg packages taught: the seam-selection rule, that a
mispointed patch can hang rather than fail, and the copy-preamble-then-
let-ruff-prune order for test splits.

Adds docs/shell-split-recipes.md for the linux_configuration tranche,
where there is no pass count to verify against - names the two live
systemd units that point at repo paths and the jscpd trap on the first
multi-lib commit. Decision 10 records the user's call to fix lint rather
than relocate a per-file-ignore.

The handoff had grown to 280 lines splitting it out, which would have
been a new violation; it and both recipe docs are now under the cap.

# Shell split recipes for the 250-line cap
Split out of `refactor_claude_todo_resume.md` (which is itself capped).
Applies to `linux_configuration/` and `phone_focus_mode/`.
`linux_configuration` and `phone_focus_mode` have **no test suite and no
coverage gate**, so none of the above transfers. Decision 6 governs:
`bash -n` + `shellcheck` + `systemctl cat` path checks, and **never execute an
enforcement script that mutates the live system or the phone.**
- After each split, `bash -n` and `shellcheck` the entry script *and* every new
lib. Neither catches a lib that is never sourced.
- So also: for each new `lib/*.sh`, grep the entry script for the `source`/`.`
line naming it, and confirm the path resolves from where the script actually
runs (`${BASH_SOURCE[0]%/*}` or absolute — never a bare relative `./lib/`).
- **Two live units point at repo paths** and break if a file moves or is
renamed. `systemctl cat` them after touching either:
- `/etc/systemd/system/dns-blocklist-refresh.service` →
`scripts/single_use/features/setup_dns_blocker.sh refresh`
- `/etc/systemd/system/media-organizer.service` →
`scripts/single_use/utils/organize_downloads.sh`
Every other in-repo unit references an installed copy under `/usr/local/`,
so those are only at risk if the *installer* is what you split.
- Prefer files that **nothing** references first — pure lint risk.
- Watch **jscpd** on the first multi-lib commit: repeated `set -euo pipefail` +
source-guard headers across several new libs is exactly what pushes
duplication toward the 2% threshold, and it only fires on the real
`git commit`.
