Bastien Chanot c0fddc6f94 feat(install): system-wide low-disk login warning via /etc/profile.d

Add etc/profile.d/disk-usage-warning.sh (POSIX sh) that warns in bold
red at login when / or /home cross 85% usage. Deployed system-wide via
install_disk_warning() (sudo install -D -m 0644), gated inside the
apt-get block since df --output=pcent and /etc/profile.d are GNU/Debian
conventions absent on macOS. Idempotent and re-runnable.

CLAUDE.md — config (personal dotfiles)

Project context for Claude. Global preferences in ~/.claude/CLAUDE.md apply on top.

What this is

Personal dotfiles repo. Archetype: dotfiles-meta (meta/config, not an application). Produces vim + bash configuration deployed by install.sh. Private/personal audience.

Public: no
Database: none
Stack: POSIX/bash shell scripts + vimscript
Distribution: git clone + ./install.sh <target>

Layout

remote-install.sh     curl|bash bootstrap: ensure git, clone/pull, run install.sh
install.sh            one-shot installer (OS auto-detected)
vim/vimrc             vim config (pathogen, molokai, syntastic, NERDTree)
vim/autoload/         pathogen loader (committed)
vim/colors/           molokai colorscheme (committed)
bash/bashrc-{linux,osx}          OS-detected bashrc
bin/{dt,dtach-router,claude-provider}   CLI scripts deployed to ~/.local/bin
etc/profile.d/disk-usage-warning.sh     login-time low-disk warning → /etc/profile.d (Linux only)
.claude/{tasks,memory,audits}/   Claude working state

pymupdf/markdown_py are NOT tracked — they are pipx entry-point shims, recreated by pipx install PyMuPDF Markdown in install.sh. claude-provider reads $OPENROUTER_API_KEY from the env — never hardcode it (the original had a live key; it was scrubbed — see decisions/blockers).

Commands

Task	Command
Lint	`shellcheck .sh bash/bashrc-`
Syntax check	`bash -n install.sh remote-install.sh`
Install	`./install.sh` (OS auto-detected)
Remote install	`curl -fsSL <raw>/remote-install.sh \| bash`

No build, no test suite. Lint = shellcheck.

Conventions

Shell scripts: #!/usr/bin/env bash, set -euo pipefail, quote all expansions, keep shellcheck clean.
Installer must stay idempotent (re-runnable without breaking state) and use $SCRIPT_DIR-relative paths.
bashrc files: tabs for indentation (existing style). Style nits (legacy backticks) tolerated — don't churn.
No secrets in any tracked file. Use placeholders if config ever needs tokens.

Known issues (see .claude/audits/ONBOARD_REPORT.md)

vim/vimrc GenerateClassC uses bare name instead of a:name → :ClassC errors (E121). Vim domain, not yet fixed.
bashrc files use legacy backticks (SC2006) — cosmetic.
