Adds three small but high-leverage presentation tweaks for v0.1:
1. internal/cli/style is a new ~70 LOC package with Pass/Fail/Warn/
Dim/Bold helpers. Each is TTY-gated and obeys NO_COLOR. No
external dep. Wired into the doctor PASS/FAIL/WARN status, the
"banger:" error prefix on stderr, and the dim 'ready in <elapsed>'
line.
2. internal/cli/errors translates rpc.ErrorResponse into user-facing
text. operation_failed becomes invisible (the message wins);
not_found, already_exists, bad_request, bad_version, unauthorized,
unknown_method get short labels; unknown codes pass through. The
daemon-attached op_id lands in dim parens — paste into
journalctl --grep to find the daemon log line that produced the
failure.
3. Tabwriter config converges on (0, 8, 2, ' ', 0) across every
list/table command. The vm prune confirmation table picked up the
right config; system install + system status switched from bare
"key: value\n" lines to tabular form. printVMSpecLine drops its
Unicode middle dot for an ASCII '|' so terminals without UTF-8
render cleanly.
Tests cover translateRPCError for every code, style helpers no-op
on non-TTY and under NO_COLOR. Smoke status greps switch from
"key: value" to "key value" to match the new format.
