* feat(shortcuts): default to hold Right Alt push-to-talk on first install
Double-tap Ctrl conflicts with many desktop and app shortcuts, so new
installs now use hold Right Alt (Option) in push-to-talk mode. Existing
config.json values are preserved unchanged.
Updates README, user guide, AGENTS.md, first-run dialog, website copy,
and tests to match the new defaults.
* refactor(shortcuts): trim redundant default-change test and comments
Drop the fresh-install assertion that duplicated DEFAULT_CONFIG coverage,
remove the duplicated Right-Alt rationale from config_manager, and drop a
vacuous source-string check from the settings shortcuts test.
* fix(shortcuts): align install.sh seeds and preserve legacy toggle mode
install.sh still wrote ctrl+ctrl without mode, so merges with the new
push_to_talk default became hold-Ctrl. Seed right_alt + push_to_talk for
new installs, and migrate existing shortcut-only configs to mode=toggle
so prior behavior is unchanged.
* style(config): fix black formatting after shortcuts migration
* fix(shortcuts): preserve legacy defaults when shortcuts section is missing
Existing config files without a shortcuts section previously inherited
ctrl+ctrl toggle from DEFAULT_CONFIG. Pin those historical defaults on
upgrade so the new first-install Right Alt push-to-talk defaults do not
silently change behavior.
* docs(agents): unwrap hard-broken dictation control paragraph
Keep the AGENTS.md paragraph as a single line like the surrounding prose.
