fix(sweep): recognize anchored /.ai/ style; warn on publicly reachable tooling

sweep-gitignore-tooling.sh decided gitignore-mode with an exact unanchored match on `.ai/`, so a project using the anchored `/.ai/` form was misclassified as track-mode and silently skipped — which left .emacs.d's tracked tooling on a public GitHub mirror until its 2026-06-30 scrub. Both forms now count for mode detection and per-pattern presence, and appended lines follow whichever style the file already uses.

Track-mode projects also get a new check: tracked tooling paths combined with a non-cjennings.net remote draw a loud WARN, since a track-mode repo on a public host is the exposure the convention exists to prevent. The convention itself is now written down in protocols.org: a non-cjennings.net remote means the tooling set is gitignored, a deliberate team-shared config being the only explicit exception, and a private remote is not proof of privacy because a server-side mirror hook republishes invisibly.

From the .emacs.d handoff (2026-06-30 tooling-exposure broadcast).

 **The gitignore set follows that same decision.** A project that gitignores =.ai/= (the code-project case) gitignores the whole personal-tooling set: =.ai/=, =.claude/=, =CLAUDE.md=, =AGENTS.md=. =.claude/= is rulesets-owned — copies of =claude-rules/*.md= plus the language bundle's rules, hooks, and settings — and re-synced from rulesets on every startup, so git isn't how it travels between machines; ignoring it also keeps those private rule copies out of the repo, which ignoring =CLAUDE.md= alone would miss. A track-mode project (personal/doc repos, or a team repo that shares config with teammates who don't run rulesets) tracks the set instead. =install-ai.sh= writes the full set at bootstrap in gitignore mode; =scripts/sweep-gitignore-tooling.sh= backfills it idempotently across existing gitignore-mode projects when the set grows.
 
+**Public reachability decides harder than project type.** Any repo whose remotes include a non-cjennings.net host gitignores the tooling set, whatever kind of project it is — the only exception is a team repo that deliberately shares the config, decided explicitly, never by default. And a private remote is not proof of privacy: a server-side =post-receive --mirror= hook republishes invisibly from the client (the 2026-06-30 =.emacs.d= exposure rode exactly that — a cjennings.net remote mirroring to public GitHub). The sweep recognizes both the anchored (=/.ai/=) and unanchored (=.ai/=) ignore styles — an anchored-style project used to be misread as track-mode and silently skipped — and warns when tracked tooling can reach a non-cjennings.net remote.

 **Credential-leak concern: gate it on project type, not on the credential itself.** A tracked secret, token, or credentials doc is only a public-leak risk where the repo can reach a public remote — that is, *code projects pushed to public GitHub*, which is exactly why those gitignore =.ai/= and =.claude/=. For *personal / documentation projects* (the =~/projects/= set: elibrary, home, finances, health, philosophy, etc.), the git remote is a private single-user repo on =cjennings.net=, so tracked credentials inside =.ai/= files are fine — that's the design, the project history IS the project. Do NOT raise a leak warning or suggest gitignoring a secret for these. When the question "is this a leak / should we gitignore this secret?" comes up, decide it on *which kind of project and remote* this is, never on the mere presence of a credential in a tracked file.
