refactor(gitea-branches): retrofit to the ADR-0020 context contract

Description 688 -> 282 chars, body 435 -> 293 words, Gotchas 5 entries/54% of
body -> 3/23.5%. Clears the description FAIL and the Gotchas suggestion.

Cut the second trigger register (six re-quoted user phrasings) and the capability
enumeration; both moved to a new Boundaries section in the skill's own README.
Kept all three boundary clauses -- git-branches, git-history and gitea-prs each
defend a real activation steal, and gitea-prs is now the only guard on the
branch/PR collision in either direction since gitea-prs's own retrofit narrowed
its boundary to issues. Written as one arrow per target: the resolver extracts
only the first name per arrow clause, so conjoined targets go unchecked.

Two Gotchas deleted -- one paraphrased the step below it (its non-obvious half,
the get_me/list_my_repos token-scope block, was folded into that step), the other
is carried in full by references/branches.md:40-52.

Repoint two reference pointers the rename broke: branches.md and commits.md named
Gotchas by titles this retrofit changed. Now named by stable descriptors.

## Boundaries
This skill operates on the Gitea server via the MCP tools, never on your local checkout. Branch
and commit-history work against the working copy belongs to `git-branches` and `git-history`.
Branch references that only exist relative to a pull request — a PR's head or base branch, and
cross-repo fork PR heads in particular — belong to `gitea-prs`; `list_branches` cannot see a fork's
head at all.
The skill triggers on phrasings like "list branches", "create a branch", "delete a branch",
"what commits are on this branch", "show commit <sha>", and "what changed in that commit", even
when the user does not say "Gitea", as long as the repo's remote is a Gitea instance.
## Before you start
Requires a Gitea MCP server configured with a token that has `write:repository` scope. This is
