docs(demo): refresh demo materials for TUI feature drift (#1157–#1173)

[GarthDB]

Description

Refreshes all demo materials to match the current TUI after ~10 feature PRs (#1157–#1173) landed since the last update (early June / #1107–#1113), leaving the demo partly broken and out of date.

No TUI source changes — / fuzzy-find removal is treated as intentional (superseded by the :find wizard).

Related Issue

N/A — maintenance follow-up to #1157–#1173.

Motivation and Context

The demo recording scripts (auto-demo.sh A/B) had three broken areas:

1. A4 beat broken: /accentbg fuzzy-find no longer exists in the TUI (QueryView::fuzzy is never constructed, no / key handler). The Fuzzy marker sentinel would never anchor.
2. B wizard sentinels stale: Screen titles changed from Wizard · N/4 · <Name> to Step N of 4 — <Name> (feat(tui): context-sensitive help + wizard step indicator #1169/feat(tui): wizard help overlay, Esc back-stack, did-you-mean, [SEL] badge, readline #1172). The N/4 regex fallbacks survived but comments/markers were wrong.
3. B Esc behavior wrong: Esc now back-navigates one screen at a time (fix(tui): esc goes back one screen in wizard instead of cancelling #1160/feat(tui): wizard help overlay, Esc back-stack, did-you-mean, [SEL] badge, readline #1172) instead of canceling. A single Esc from Screen 4 (Confirm) only steps to Screen 3 — the old beats left the wizard open after "cancel".

Also refreshes documentation to document new features: :find wizard + faceted count badges (#1173), :validate grouping (#1165), g/G jump (#1164), y/Y yank (#1170), h/l horizontal scroll (#1166), Esc back-navigation (#1160/#1172), fuzzy palette autocomplete (#1168).

How Has This Been Tested?

• Beat scripts (A.beats.sh, B.beats.sh) reviewed against current TUI source (sdk/tui/src/find.rs, model/views.rs, wizard.rs) for sentinel accuracy
• remark linter passed on all four .md files (pre-commit hook)
• Re-recording (moon run demo:auto-record) and CI verify (moon run demo:auto-verify) should be run after merge on a machine with rmux + asciinema + CLI pre-built

Screenshots (if appropriate):

N/A — documentation/script changes only.
