deployer(ET): auto-commit from deployer run_id=531

render_task_tracker sends/edits the live card with parse_mode=HTML. _fmt_minutes
returns the literal "<1м" for a sub-minute stage; interpolated raw into HTML text
Telegram parsed "<1м" as an opening tag -> editMessageText 400 can't parse
entities -> edit_telegram EDIT_FAILED -> update_task_tracker early return
(anti-duplicate ORCH-087) -> the card froze (incident ORCH-093, message_id 18854).

Close the whole "unescaped data in HTML text" class per ADR-001: a module-local
_esc(x)=html.escape(str(x)) (never-raise) wraps every DATA slot (durations, status
label, model, effort, token/cost metrics) exactly once at the render boundary in
render_task_tracker/_stage_line. Source functions stay HTML-agnostic (_fmt_minutes
still returns "<1м"; escape on the boundary renders it visually identical as
&lt;1м, so the visible format is unchanged). Intentional MARKUP slots (num_html /
link_for / _done_link / already-escaped esc_title) are NOT escaped, so the issue
number stays a clickable <a> tag and nothing is double-escaped.

A previously-frozen card auto-recovers on the next stage transition (a new safe
render edits in place, 200) — no new code, no touch to edit_telegram /
update_task_tracker / the orphan ledger, so the ORCH-087 anti-duplicate invariant
is preserved (a transient edit failure still does not spawn a new card).

STAGE_TRANSITIONS / QG_CHECKS / check_* / notification transport / DB schema are
untouched. New tests/test_tracker_html_escape.py (TC-01..TC-11); full suite green.
