A value like `X=a` would pass the startsWith/endsWith quote check
(both `"` and `'` are single chars), then slice(1, -1) would produce
an empty string, silently dropping the value. Add length >= 2 guard
before checking for surrounding quotes.

**stopContainer (container-runtime.ts):**
- Validate container name against `^[a-zA-Z0-9][a-zA-Z0-9_.-]*$` before
passing to shell command. Rejects names with shell metacharacters
(`;`, `$()`, backticks, etc.) that could execute arbitrary commands.
- Changed return type from string to void — callers no longer build
shell commands from the return value.
**mount-security.ts:**
- Reject container paths containing `:` to prevent Docker `-v` option
injection (e.g., `repo:rw` could override readonly flags).
- Don't permanently cache "file not found" for mount allowlist — the
file may be created later without requiring a service restart. Only
parse/structural errors are permanently cached.
