Slash-command surface for the community-skill installer:
- `/skill install <github:owner/repo|https://...|<registry-name>>` parses
the spec via `InstallSource::parse`, calls `install_with_registry`, and
surfaces `NeedsApproval`/`NetworkDenied` with actionable messages
pointing at `[network]` config (we deliberately don't dispatch a modal
from the sync slash-command path; the underlying installer returns the
outcome so a future approval wiring can reuse it).
- `/skill update <name>` re-fetches and prints "no upstream change" when
the checksum matches.
- `/skill uninstall <name>` and `/skill trust <name>` both refuse to
touch system skills (no `.installed-from` marker).
- `/skills --remote` (or `/skills remote`) fetches the curated registry
through the same network gate and prints `name — description (source)`.
Internals:
- Sub-command dispatch happens in `run_skill` before activation lookup,
so a user can't accidentally activate a skill literally named
`install`. Async install/update/uninstall plumbed through
`tokio::task::block_in_place` + `Handle::current().block_on`, matching
the existing pattern in `commands/cycle.rs`.
- `installer_settings` loads `Config` on demand — `App` doesn't carry a
`Config` reference, and the cost of a single TOML parse is negligible
next to the network round-trip the install will make.
Config:
- New `[skills]` section in both `crates/tui/src/config.rs::Config` and
the workspace `crates/config/src/lib.rs::ConfigToml` with
`registry_url` (default: bundled raw GitHub index) and
`max_install_size_bytes` (default: 5 MiB).
- `merge_config` propagates the new field, default impls cover the
unset case.
