* fix(coding-agent): guard tree navigation during responses
* fix(coding-agent): simplify tree navigation regression
* fix(coding-agent): abort active run on session replacement and tree navigation
Session replacement (resume, new, fork, import) now settles the active
response in teardownCurrent before disposing the outgoing session, so the
aborted turn and its tool results persist instead of leaving a dangling
tool call. Tree navigation aborts the active response directly once the
user commits, without a confirmation gate.
* fix(coding-agent): isolate autoload-disabled package test from real home directory
The test asserted result.skills is exactly empty, but resolve() also
scans ~/.agents/skills via getHomeDir(). On machines where that
directory is populated the test failed; CI runners have no
~/.agents/skills, so it always passed there. Stub HOME to the temp
dir with the same save/restore pattern used by neighbouring tests.
* fix(coding-agent): use vi.stubEnv for home directory isolation
Replaces the manual try/finally save/restore with vi.stubEnv plus
vi.unstubAllEnvs in afterEach, shrinking the fix to two added lines.
* fix(coding-agent): plant decoy user skill so the empty-skills assertion cannot pass vacuously
With an empty sandbox, result.skills equal to [] could not distinguish
the package skill being correctly excluded from skill resolution being
broken entirely. A decoy skill in the stubbed HOME's .agents/skills
proves scanning still works while the package skill stays excluded.
* fix(coding-agent): simplify home isolation test
