fix(cli): survive ktx.yaml version skew and derive repo ownership from disk (#293)

* fix(cli): survive ktx.yaml version skew and derive repo ownership from disk

Loading ktx.yaml is now tolerant of keys this ktx version does not
recognize: they are stripped from the in-memory config (the file on disk
is never rewritten) and reported by ktx status as non-blocking warnings,
while invalid values on recognized fields still fail hard. Repo
ownership is derived from observed state (a .git directory plus a root
ktx.yaml) instead of a ktx.managed git-config marker, so projects
created by any past or future ktx classify identically. initKtxProject
now runs an explicit foreign-repo pre-check and writes ktx.yaml before
initializing git, so an interrupted init leaves only recoverable
residue instead of a bare .git misread as foreign.

* style(cli): trim comment blocks to constraint-only notes

* docs(agents): require constraint-only code comments

* Classify whether ktx may own a git repository rooted exactly at `dir`.
* Classify whether ktx may own a git repository rooted exactly at `dir`. A root
* `ktx.yaml` is the ownership signal; the working tree decides, not git history,
* because older ktx versions left `ktx.yaml` uncommitted (it holds secret refs).
*
* - `unowned`: there is no git repository for ktx to avoid here ktx may
* `git init`. Covers a fresh standalone directory, a fresh directory nested
* inside a parent repo, a path that does not exist yet, and a path that is not
* a directory at all (whether the path is a usable project directory is a
* separate concern for the caller to validate).
* - `ktx-managed`: `<dir>/.git` is a directory carrying ktx's ownership marker.
* - `foreign`: a repo ktx did not create a `.git` directory without the marker,
* or a `.git` *file* (a linked worktree). ktx must never adopt or mutate it.
* - `unowned`: no repo here (including a missing or non-directory path) ktx may `git init`.
* - `ktx-managed`: `<dir>/.git` is a directory and `ktx.yaml` sits at the root.
* - `foreign`: any other repo no root `ktx.yaml`, or a `.git` *file* (a linked
* worktree). ktx must never adopt or mutate it.
*
* Reads only `<dir>/.git` directly and never walks up the directory tree, so the
* classification of a project dir never depends on whether a parent repo exists.
* Shared by `GitService.initialize()` (the invariant) and the setup wizard (the
* pre-flight guidance) so both decide ownership from the same rule.
* Reads only `<dir>` itself; never walks up, so a parent repo cannot change the answer.
