fix(claudbg-u28r): use blue/white search highlight for light mode legibility

Also close claudbg-4g3l, claudbg-ltt0, claudbg-37cj as already implemented.
Fixes pre-existing fmt issues in agents.rs, sessions.rs, filter.rs, and TUI files.

 Add `--color` / `--no-color` as a global CLI flag (available on all commands). When not specified, auto-detect: enable color if stdout is a tty and NO_COLOR is unset/empty. Honor the NO_COLOR environment variable (any non-empty value → disable color), per the NO_COLOR spec. This flag controls all ANSI output in the CLI (transcripts etc).
+
+## Summary of Changes
+
+Already implemented prior to this bean being created. `GlobalOpts` in `src/cli.rs` has `--color`/`--no-color` flags and `color_enabled()` respects `NO_COLOR` env var per spec.

 Both `sessions list` and `agents list <session-id>` should default to showing only the 10 most recent entries (sorted most-recent-first). Add a `--limit=<N|all>` flag to override: accepts an integer (e.g. `--limit=50`) or the keyword `all` to show everything.
+
+## Summary of Changes
+
+Already implemented prior to this bean being created. The `Limit` enum with `Count(10)` default is in `src/cli.rs`, applied via `--limit` flag on both `sessions list` and `agents list`.

 Running `claudbg sessions` with no sub-command should behave identically to `claudbg sessions list`. Note: `claudbg agents` does NOT get this treatment since agents list requires a session ID.
+
+## Summary of Changes
+
+Already implemented prior to this bean being created. `src/main.rs` uses `cmd.unwrap_or(SessionsCmd::List { limit: Default::default(), filter: vec![] })` so `claudbg sessions` defaults to `sessions list`.

 In light mode, the selected/highlighted search match text is too dark to read against the highlight background. The search highlight colors need to be adjusted to be legible in both light and dark mode.
+
+## Summary of Changes
+
+Changed `SEARCH_HIGHLIGHT` style in `src/tui/screens/transcript.rs` from `bg(Color::Yellow).fg(Color::Black)` to `bg(Color::Blue).fg(Color::White)`. Blue/white is universally readable in both light and dark terminal themes.
