Why

Searching an org for a team's repos by name caught every name that merely contained the term: *billing* matches rebilling. Narrowing the result meant starting the search over. Repos added later with clone --save could also be rewritten by the next gitten setup.

Changes

• Names are words. A name filter without wildcards matches whole words of the repo's name. billing matches billing-api, team-billing and BillingPortal, but not rebilling. Words split at punctuation, camelCase, and where letters meet digits. With *, ? or [...] it's still a glob over the whole name.
• Pick from the list. Setup's preview now says how many repos each name matched, and offers three choices: track them all, pick from the list (a checklist with every match ticked), or change the search. gitten clone with a selection asks the same on a terminal before cloning. Repos you untick go in the rule's new skip:, matched by exact name, and new matches still arrive.
• Setup keeps rules it didn't write. Each tracked owner now remembers its rule, an owner can have several, and setup only edits rules for an organization, a group, or the account's own repos. Search rules and other users' rules are left as they are. Before, a re-run could take a search rule for your own repos and rewrite it, or merge two rules for one org into one.
• Smaller output fixes. clone says what it searches and where (Searching acme's repos on github.com...), and discover's preview mentions clone ... --save for tracking more.
• Docs. The README gets a Finding your repos walkthrough, first time and later, plus a "Matching names" table that a test checks against the matcher. SPEC, config.example.yaml and the examples are updated too.

Test plan

• go test -race ./..., vet, gofmt, golangci-lint, and the full e2e suite run uncached.
• Unit tests:
  • name matching, including every row of the README table;
  • skip filtering and validation;
  • a re-run keeps a search rule, another user's rule, and a second rule for an org, and removes only an untracked owner's rule;
  • tracksFor, matchCounts, and trackLabel with skip.
• Drove the real wizard in a pseudo-terminal: preview with by name: gitten 1, pkg 1, then pick from the list and untick one. The review showed skip: [gitten], and the clone question said 1 repo.
• Live against GitHub: clone --org charmbracelet --name bubbletea matches bubbletea and bubbletea-app-template, not bubbles.
