Update FlowStudio Power Automate skills (#1664)

* feat(flowstudio): align Power Automate skills with MCP server v1.1.6

Foundation skill (flowstudio-power-automate-mcp) rewritten to use the
server's new tool_search and list_skills meta-tools (v1.1.5+) for
discovery instead of cataloging every tool by hand. Cut from 519 to
295 lines. New "Which Skill to Use When" intent-keyed decision tree
points at the four specialized skills.

Build/debug/governance/monitoring updated for use-case framing. Tools
that genuinely cross tiers (e.g. debug skill borrowing
get_store_flow_summary) are correct when the workflow needs them — the
split between skills is by use-case intent, not by tool partition.

Build skill: new Step 3a Resolving Dynamic Connector Values covers
get_live_dynamic_options outer-parameter auto-bridge (v1.1.6+) and the
AadGraph user-picker fallback via shared_office365users.SearchUserV2
(replaces broken builtInOperation:AadGraph.GetUsers).

Debug skill: Outlook user-picker failure note pointing at the fallback.

Monitoring skill description disambiguates from the server's monitor-flow
tool bundle (runtime control of a single flow) — this skill is
tenant-wide health analytics over the cached store.

All 5 skills validate via npm run skill:validate; line endings LF only;
codespell clean; auto-regenerated docs/README.skills.md included.

* fix(flowstudio): remove deprecated tool references

The v1.1.5 MCP server release marked 5 tools [DEPRECATED] but the
previous alignment commit missed them. Replacements per server source:

- get_live_flow_http_schema → read trigger.inputs.schema from get_live_flow
- get_live_flow_trigger_url → read trigger.metadata.callbackUrl from get_live_flow
- get_store_flow_trigger_url → get_store_flow.triggerUrl field
- get_store_flow_errors → get_store_flow_runs(status=["Failed"])
- set_store_flow_state → set_live_flow_state

Touches build, debug, governance, monitoring SKILL.md and the
foundation skill's tool-reference.md. Remaining mentions of the
deprecated names are intentional — they live in deprecation notices
naming the obsolete wrapper alongside its replacement.
