feat(t5): add support for Ziguang ZG25Q64B flash chip

Add flash table entry for Ziguang (紫光) ZG25Q64B SPI-NOR flash
(MID 0x1760cd, 8 MiB) with correct write-protection register config.

WP config derived from vendor tool USB packet capture:
- SR1 protect bits: BP2/BP1/BP0 (mask 0x0038)
- SR2: no protection bits
- SR read: 0x05/0x35, SR write: 0x01/0x31

refactor(tests): standardize string quotes and improve formatting in …

…chip manifests and constants tests

test: add T2 switch demo firmware for manual testing

ci: temporarily push only latest.json to Gitee

fix(cli): handle AuthReadEmpty milestone in reporter match

fix(flash): file picker opens to last firmware directory instead of t…

…emp dir

Derive defaultPath from the existing firmware path so the native file
dialog opens in the directory of the previously selected firmware file,
rather than falling back to the system temp dir.

feat(settings): add theme style dropdown for tuyaopen-ide theme

feat: add serial debug feature (#37)

Add a new serial debug page for monitoring and interacting with serial
  ports. Key capabilities:

  - Port connection with configurable baud rate and persistent settings
  - Real-time data display with RX/TX direction badges and timestamps
  - Keyword search with in-line highlighting and auto-scroll to first match
  - Auto-save session log to file with status indicator
  - Device reset button using chip platform from flash store
  - Port kept alive across page navigation via keep-alive

  Also fix keep-alive route keying by component name to isolate per-route
  caches, and remove the reset button from the firmware-flash connection
  bar (now lives in serial-debug only).

ci(release): pre-install Gitee sync deps on self-hosted runner

ci(release): install Gitee sync dependencies
