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
