Subject: [PATCH 1/3] feat(git): add commit context collector

Adds `getCommitContext()`, which gathers the changes a commit message should
describe. Part 1 of 4 for AI commit-message generation; nothing consumes it yet.

Every command runs through `execFile` with an argument array, so no path is ever
interpolated into a shell string, and both listings are read NUL-delimited:
`git diff --cached --name-status -z` for the index and
`git status --porcelain=v1 -z --untracked-files=all` for the working tree. Their
rename records disagree on field order - the diff form emits the original path
first, porcelain the new one - so each has its own parser. Copy records carry two
paths as well and appear whenever `diff.renames = copies` is configured, so they
are consumed correctly even though copy detection is never requested; reading one
path where there are two would shift every later record onto the wrong file.

The result is a typed `CommitContextResult` rather than a string. Failures that
are expected rather than exceptional - an oversized diff exceeding `maxBuffer`, a
repository git refuses to describe - come back as a reason, so the function never
rejects. Branch and recent subjects are collected as context, and tolerate the
unborn-HEAD case where `git log` fails outright.

Untracked files have no diff, so a bounded head of each one is read directly:
without it an untracked-only change reaches the model as a bare list of
filenames. Only the first 2KB of each file is read, so an enormous file costs
nothing, and anything containing a NUL byte is skipped as binary.

Output is capped by characters as well as lines. A line limit alone is not a
bound - one minified or generated file can be a single line of several megabytes.

Staged changes are collected first, since that is what a commit will actually
contain. When nothing is staged it falls back to the working tree so callers
still have something to summarize before staging. That fallback deliberately runs
`git diff` rather than `git diff HEAD`: the index is known to be empty at that
point so the output is identical, but `HEAD` does not resolve in a repository
without an initial commit, where it would fail.

Subject: [PATCH 2/3] feat(git): describe only staged changes

Falling back to the working tree meant the message could describe changes the
commit would not contain. An empty index now returns `nothing-staged`, which the
caller turns into advice to stage something, and `no-changes` is reserved for a
genuinely clean tree.

Removes the untracked-file reading that only the fallback needed.

Subject: [PATCH 3/3] feat(commit-message): add prompt template and generator
 service

Turns collected git context into a commit message. Part 2 of 4 for AI
commit-message generation; the VS Code wiring that calls this follows.

The prompt exposes the context as separate placeholders - `${branch}`,
`${recentCommits}`, `${changedFiles}` and `${diff}` - rather than one opaque
blob, so a user editing the prompt in Settings -> Prompts can reorder or drop any
of them independently. The diff is fenced in explicit markers and labelled as
repository content, since it reaches the model verbatim and can contain
instruction-like text.

`generator.ts` is deliberately free of VS Code: it takes git context and provider
settings and returns cleaned text, locating no repository and writing nowhere, so
it can be exercised without the extension host. Its tests load no `vscode` mock
at all, which is what keeps that honest.

An empty response is now a failure rather than a success. A model that answers
with nothing, or with an empty code fence, previously produced an empty message
that a caller would happily write over whatever the user had already typed.

`config.ts` resolves which profile to generate with. The chosen profile is only a
preference: a saved id outlives the profile it points at, and a profile can be
deleted between reading the state and looking it up, so both cases fall back to
the active configuration instead of stopping generation.
