fix: improve CLI text padding, word-wrap for responses and verbose tool output (#9920)

* feat(skills): add fitness-nutrition skill to optional-skills

Cherry-picked from PR #9177 by @haileymarshall.

Adds a fitness and nutrition skill for gym-goers and health-conscious users:
- Exercise search via wger API (690+ exercises, free, no auth)
- Nutrition lookup via USDA FoodData Central (380K+ foods, DEMO_KEY fallback)
- Offline body composition calculators (BMI, TDEE, 1RM, macros, body fat %)
- Pure stdlib Python, no pip dependencies

Changes from original PR:
- Moved from skills/ to optional-skills/health/ (correct location)
- Fixed BMR formula in FORMULAS.md (removed confusing -5+10, now just +5)
- Fixed author attribution to match PR submitter
- Marked USDA_API_KEY as optional (DEMO_KEY works without signup)

Also adds optional env var support to the skill readiness checker:
- New 'optional: true' field in required_environment_variables entries
- Optional vars are preserved in metadata but don't block skill readiness
- Optional vars skip the CLI capture prompt flow
- Skills with only optional missing vars show as 'available' not 'setup_needed'

* fix: increase CLI response text padding to 4-space tab indent

Increases horizontal padding on all response display paths:

- Rich Panel responses (main, background, /btw): padding (1,2) -> (1,4)
- Streaming text: add 4-space indent prefix to each line
- Streaming TTS: add 4-space indent prefix to sentences

Gives response text proper breathing room with a tab-width indent.
Rich Panel word wrapping automatically adjusts for the wider padding.

Requested by AriesTheCoder.

* fix: word-wrap verbose tool call args and results to terminal width

Verbose mode (tool_progress: verbose) printed tool args and results as
single unwrapped lines that could be thousands of characters long.

Adds _wrap_verbose() helper that:
- Pretty-prints JSON args with indent=2 instead of one-line dumps
- Splits text on existing newlines (preserves JSON/structured output)
- Wraps lines exceeding terminal width with 5-char continuation indent
- Uses break_long_words=True for URLs and paths without spaces

Applied to all 4 verbose print sites:
- Concurrent tool call args
- Concurrent tool results
- Sequential tool call args
- Sequential tool results
