fix(#2376): emit absolute subagent-facing paths from init/state, convert workflow literals (#2428)

* fix(#2376): emit absolute subagent-facing init/state paths

Make init.* and state.* path fields absolute rather than cwd-relative
so subagent prompts resolve correctly regardless of working directory.
Adds intel_dir/conflicts_path/requirements_path/roadmap_path/state_path
to cmdInitIngestDocs, an absolute debug_dir to cmdStateLoad, and
replaces bare .planning/... literals in 12 workflow Agent() prompt
blocks with the absolute init-JSON path fields. Includes decoy-cwd
regression tests and realpath'd tmpdir fixtures for macOS.

Squashed rebase of the #2376 commit series onto a fresh origin/next
(previous merge ee25543a1 was against a now-stale next).

* chore(#2376): add changeset

* chore(#2376): regenerate golden fixtures + workflow size baseline

Regenerated after rebasing the absolute-path fix onto current next
(picks up #2351's run-with-timeout content in execute-phase.md too).

* fix(#2376): trim execute-phase.md redundancy to stay under the size margin

* chore(#2376): regenerate golden/size baseline after rebase onto next
