feat(frontend): render slash-skill activations as inline chips (#3981)
* feat(frontend): render slash-skill activations as inline chips

Show an explicit `/skill` activation as a compact inline chip in both the
composer and the chat transcript instead of raw slash text.

- Composer: selecting a skill suggestion stores it as a removable chip
  aligned inline with the textarea; the leading `/skill ` prefix is
  reattached only at submit time, so the backend activation protocol is
  unchanged. Backspace on an empty input or the chip's close button clears
  it; history navigation is disabled while a chip is active.
- Transcript: human messages that begin with `/skill` render the skill as a
  read-only chip followed by the task text.
- Add a shared `core/skills/slash.ts` (`parseSlashSkillReference` +
  `resolveSlashSkillDisplay`) mirroring the backend `slash.py` gate, so the
  transcript only shows a chip when the skill actually exists and is enabled.
  This removes a duplicated regex/reserved-name list and keeps display
  semantics consistent with backend activation.

Add unit tests for the shared slash parser and extend the chat e2e to assert
the composer still submits `/skill <task>` after showing a chip.

* chore(frontend): format chat e2e test

* refactor(skills): address slash-skill chip review feedback

Follow-up to the inline slash-skill chip PR, resolving three second-order
review findings:

- Drive the reserved-command set and skill-name grammar from a shared
  contracts/slash_skill_contract.json instead of a hand-copied
  "keep in sync" pair. slash.ts and slash.py now reference the fixture, and
  contract tests on both sides fail CI if either drifts.
- Extract a shared SlashSkillChip so the composer and transcript chips stay
  in lockstep, and normalize the off-scale /8 and /12 opacity steps to the
  standard /10 and /20 tokens.
- Split HumanMessageText into a pure parse gate plus a slash-only subtree
  that owns the useSkills() lookup, so a skill-enabled toggle no longer
  re-renders every plain-text human turn.

Verified: frontend eslint + tsc clean, pnpm test 572 pass (incl. new
slash-contract test); backend slash contract + slash-skills tests 31 pass.

* style(tests): sort slash skill contract imports

* fix(composer): inline the slash-skill text so the chip aligns with input

Address the "composer body layout change" review on #3981 by rendering the
active skill as an inline chip in the same text flow as the prompt, rather
than a separate flex row that drifted the box model across states.

- Render the chip + prompt inside one leading-6 wrapper and edit the prompt
  through a `contentEditable` span, so the chip sits inline with the first
  line and long/multi-line input wraps naturally back to the container edge.
- Align the chip with `align-top`: its h-6 (24px) height matches the text
  line height, so chip and first-line centers coincide exactly (measured
  delta 0), fixing the chip being raised above the baseline.
- Restore the placeholder in chip mode via a `data-empty` CSS `::before`,
  which also gives the empty editable span width so it is no longer treated
  as hidden.
- Widen the IME helper to `HTMLElement` and route the span's keydown/paste
  through the shared skill-suggestion, prompt-history, backspace-to-clear,
  and IME-composition handlers so contentEditable behaves like the textarea.
- Extend chat.spec.ts to drive the inline skill editor instead of the
  textarea after a chip is shown.

* style(frontend): fix composer class order formatting

* fix(composer): break long unbroken input inside the slash-skill row

The inline slash-skill editor wrapped with `break-words`
(overflow-wrap: break-word), which only moves an over-long token to the
next line before breaking it. A long unbroken string therefore started
on the line below the chip, and when the string contained a break
opportunity such as a hyphen the browser wrapped there and pushed the
remaining run to the next line, leaving a wide gap on the right.

Switch to `break-all` (word-break: break-all) so the text fills each
line from the chip and packs tightly regardless of hyphens or CJK.
