* fix(commands): keep line breaks from standalone voice commands
Two stacked defects ate the newline "new line" / "new paragraph"
produce when spoken alone:
* _normalize_segment_text stripped all leading whitespace, so the
command's leading newline never reached the injector (a clean
"new line" segment was dropped entirely).
* whisper.cpp transcripts arrive punctuated ("New line."), which
missed the exact-match ladder and left a stray "." after the
substituted break, injected as ". ".
Normalize now strips only spaces/tabs, and the generic path
substitutes on a punctuation-stripped core when the whole segment
is command phrases, so engine edge punctuation cannot leak while
real text keeps it.
Fixes#955
* fix(injection): deliver newline-only segments to the focused app
inject_text treated whitespace-only text as empty and returned early,
so the "\n" a standalone "new line" now correctly produces was
discarded before any backend ran ("Empty text provided, skipping
injection"). Only a truly empty segment is skipped; whitespace-only
input is typed/pasted verbatim (xdotool types "\n" as Return).
Space/tab-only segments never reach this point: segment normalization
strips them upstream.
Fixes#955
* fix(injection): keep skipping space/tab-only segments
The previous commit let every whitespace-only string through, which
also delivered bare spaces and tabs a caller never wants typed.
Narrow the skip to text with no content outside space/tab so "\n"
still reaches the backend while " " stays a no-op (the pre-existing
test_empty_text_injection contract).
Fixes#955
* fix(injection): deliver newline segments over IBus too
IBusTextInjector.inject_text had the same whitespace guard and dropped
"\n" before it reached the engine socket; narrow it the same way so
a newline-only segment is sent while space/tab-only stays a no-op.
Also let capitalize_sentences uppercase the first letter after leading
whitespace, so Vosk + auto_capitalize keeps working on "\n hello".
Covers Greptile's findings: real-socket test for the IBus path, the
capitalize regression via the main() callback seam, and type hints on
the new injector tests.
Fixes#955
* test(injection): add type hints to new IBus socket test
AGENTS.md requires hints on every signature; the Greptile review
flagged the new test for missing them.
